Nebra sky disc

<h2 id="discovery">Discovery</h2>
The disc, together with two bronze <a href="/facts/Swords/HoomVtF9">swords</a>, two sets of remains of <a href="/facts/Axe/caIr6REq">axes</a>, a <a href="/facts/Chisel/b3c4f1rH">chisel</a>, and fragments of spiral armbands were discovered in 1999 by Henry Westphal and Mario Renner while they were <a href="/facts/Treasure-hunting/LTdFM5I1">treasure-hunting</a> with a metal detector. The detectorists were operating without a license and knew their activity constituted <a href="/facts/Looting/7utcsI9z">looting</a> and was illegal. Archaeological artefacts are the property of the state in Saxony-Anhalt. They damaged the disc with their spade and destroyed parts of the site. The next day, Westphal and Renner sold the entire hoard for 31,000 <a href="/facts/Deutsche_Mark/kCwqeMkt">DM</a> to a dealer in <a href="/facts/Cologne/U2qmyGga">Cologne</a>. The hoard changed hands, probably several times, within Germany during the next two years, being sold for up to a million DM. By 2001 knowledge of its existence had become public.
In February 2002, the state archaeologist, Harald Meller, acquired the disc in a police-led sting operation in <a href="/facts/Basel/EzXbzbUx">Basel</a> from a couple who had put it on the <a href="/facts/Black_market/HDL3tQDz">black market</a> for 700,000 DM.<a class="footnote-ref" id="fnref:20" href="#fn:20">20</a> The original finders were eventually traced. In a plea bargain, they led police and archaeologists to the discovery site. Archaeologists opened a dig at the site and uncovered evidence that supported the looters' claims. There were traces of bronze artefacts in the ground, and the <a href="/facts/Soil/5Ddpr3QM">soil</a> at the site matched soil samples found clinging to the artefacts. The disc and its accompanying finds are held by the <a href="/facts/Halle_State_Museum_of_Prehistory/vJM5ojpg">State Museum of Prehistory</a> in <a href="/facts/Halle_(Saale)/hJ3EBuMn">Halle</a>, <a href="/facts/Saxony-Anhalt/XWDDbRvA">Saxony-Anhalt</a>, <a href="/facts/Germany/paluuWBX">Germany</a>.
The two looters received sentences of four months and ten months, respectively, from a <a href="/facts/Naumburg/6kPqsoV9">Naumburg</a> court in September 2003. They appealed, but the Appeals Court raised their sentences to six and twelve months, respectively.
The discovery site is a <a href="/facts/Prehistory/52D6oKM4">prehistoric</a> <a href="/facts/Enclosure_(archaeology)/BmxK8hE1">enclosure</a> encircling the top of a 252 metres (827 ft) elevation in the Ziegelroda Forest, known as Mittelberg ("central hill"), some 60 kilometres (37 mi) west of <a href="/facts/Leipzig/KIqgMgLN">Leipzig</a>. The surrounding area is known to have been settled in the <a href="/facts/Neolithic/wRS0Bnh4">Neolithic</a> era, and Ziegelroda Forest contains approximately 1,000 <a href="/facts/Tumulus/VyjgAGsu">barrows</a>.
At the enclosure's location, the sun seems to set every summer <a href="/facts/Solstice/3vEDtAhg">solstice</a> behind the <a href="/facts/Brocken/LdUECyaK">Brocken</a>, the highest peak of the <a href="/facts/Harz/NWFcnNhd">Harz</a> mountains, some 80 kilometres (50 mi) to the northwest. The treasure hunters claimed the artefacts were discovered within a pit inside the bank-and-ditch enclosure.

<h2 id="dating">Dating</h2>

Axes and swords found buried with the disc were dated typologically to c. 1700–1500 BCE. Remains of birch bark found in the sword hilts have been <a href="/facts/Radiocarbon_dating/qjNglhKP">Radiocarbon dated</a> to between 1600 and 1560 BCE, confirming this estimate. This corresponds to the date of burial, at which time the disc had likely been in existence for several generations.<a class="footnote-ref" id="fnref:21" href="#fn:21">21</a> Analyses of metal radioactivity and the corrosion layer on the disc further support the early Bronze Age dating.<a class="footnote-ref" id="fnref:22" href="#fn:22">22</a><a class="footnote-ref" id="fnref:23" href="#fn:23">23</a>

<h2 id="origin-of-the-metals">Origin of the metals</h2>
According to an initial analysis of trace elements by <a href="/facts/X-ray_fluorescence/eIUz3wwS">x-ray fluorescence</a> by E. Pernicka, then at the <a href="/facts/Freiberg_University_of_Mining_and_Technology/Mjskj6vb">University of Freiberg</a>, the copper originated at <a href="/facts/Bischofshofen/1PFjjwtM">Bischofshofen</a> in Austria, whilst the <a href="/facts/Gold/1znknojp">gold</a> was thought to be from the <a href="/facts/Carpathian_Mountains/I3TkYUjj">Carpathian Mountains</a>.<a class="footnote-ref" id="fnref:24" href="#fn:24">24</a> A more recent analysis found that the gold used in the first development phase (see below) was from the <a href="/facts/Carnon_River/alHeneDm">River Carnon</a> in southern <a href="/facts/Cornwall/9A3TftFP">Cornwall</a> in England.<a class="footnote-ref" id="fnref:25" href="#fn:25">25</a> The tin present in the bronze was also of Cornish origin.<a class="footnote-ref" id="fnref:26" href="#fn:26">26</a>

<h2 id="history">History</h2>
As preserved, the disc was developed in four stages:

<ol><li>Initially the disc had thirty-two small round gold circles, a large circular plate, and a large crescent-shaped plate attached. The circular plate is interpreted as either the <a href="/facts/Sun/CadPCVHh">Sun</a> or the <a href="/facts/Full_Moon/NRMWFPh2">full Moon</a>, the crescent shape as the <a href="/facts/Lunar_phase/0JalCYrE">crescent Moon</a> (or either the Sun or the Moon undergoing <a href="/facts/Eclipse/zXeAKwyj">eclipse</a>), and the dots as <a href="/facts/Star/PFbd6ICx">stars</a>, with the cluster of seven dots likely representing a star cluster. The star cluster is thought to refer to the <a href="/facts/Pleiades/tjwtx82z">Pleiades</a>,<a class="footnote-ref" id="fnref:27" href="#fn:27">27</a> or possibly the general symbol of a star cluster.<a class="footnote-ref" id="fnref:28" href="#fn:28">28</a></li>
<li>At some later date, two arcs (constructed from gold of a different origin, as shown by its chemical impurities) were added at opposite edges of the disc. To make space for these arcs, one small circle was moved from the left side toward the centre of the disc and two of the circles on the right were covered over, so that thirty remain visible. The two arcs span an angle of 82°, correctly indicating the angle between the positions of sunsets at summer and winter <a href="/facts/Solstice/3vEDtAhg">solstice</a> at the latitude of the Mittelberg (51°N).<a class="footnote-ref" id="fnref:29" href="#fn:29">29</a><a class="footnote-ref" id="fnref:30" href="#fn:30">30</a> The arcs relate to the Sun's path – the ecliptic. Given that ancient astronomers knew the planets and many stars that mark the ecliptic, they could observe it sweep across the horizon within the arcs, in a single winter night, not just sunrise and sunset over an entire year.<a class="footnote-ref" id="fnref:31" href="#fn:31">31</a> Thus, the arcs are consistent with wholly nighttime use.</li>
<li>The final addition was another arc at the bottom, identified as a <a href="/facts/Solar_Deity/Q2CS3IHN">solar boat</a>,<a class="footnote-ref" id="fnref:32" href="#fn:32">32</a> again made of gold, but originating from a different source.</li>
<li>By the time the disc was buried it also had 38 to 40 holes punched out around its perimeter, each approximately 3 millimetres (0.12 in) in diameter. The exact number is obscured by damage to the disc edge.<a class="footnote-ref" id="fnref:33" href="#fn:33">33</a></li></ol>

<h2 id="significance">Significance</h2>

The find is regarded as reconfirming that the astronomical knowledge and abilities of the people of the <a href="/facts/European_Bronze_Age/kaqyoMry">European Bronze Age</a> included close observation of the yearly course of the Sun and the angle between its rising and setting points at the summer and winter <a href="/facts/Solstice/3vEDtAhg">solstices</a>. While much older <a href="/facts/Earthworks_(archaeology)/3gqICEsy">earthworks</a> and <a href="/facts/Megalithic/wnyXzqda">megalithic</a> <a href="/facts/Astronomical_complex/Edfklm6G">astronomical complexes</a>, such as the <a href="/facts/Goseck_circle/coRd33o3">Goseck circle</a> and <a href="/facts/Stonehenge/5TDRUktP">Stonehenge</a>, had already been used to mark the solstices, the disc presents this knowledge in the form of a portable object.<a class="footnote-ref" id="fnref:34" href="#fn:34">34</a> The disc may have had both a practical <a href="/facts/Archaeoastronomy/6yE1gmmg">astronomical</a> purpose as well as a <a href="/facts/Prehistoric_religion/Y6V3agtm">religious</a> significance.<a class="footnote-ref" id="fnref:35" href="#fn:35">35</a><a class="footnote-ref" id="fnref:36" href="#fn:36">36</a>

<h3>Calendar rule</h3>
The depiction of the <a href="/facts/Pleiades/tjwtx82z">Pleiades</a> on the disc in conjunction with a crescent moon is thought to represent a calendar rule for synchronising <a href="/facts/Solar_calendar/HWCAWfpX">solar</a> and <a href="/facts/Lunar_calendar/llUN81gP">lunar calendars</a>, enabling the creation of a <a href="/facts/Lunisolar_calendar/L2jRkjyJ">lunisolar calendar</a>.<a class="footnote-ref" id="fnref:37" href="#fn:37">37</a> This rule is known from an <a href="/facts/Ancient_history/P0fFQ8z5">ancient</a> <a href="/facts/Babylonia/J4jjdUua">Babylonian</a> collection of texts with the title <a href="/facts/MUL.APIN/gJgFXmgu">MUL.APIN</a>.<a class="footnote-ref" id="fnref:38" href="#fn:38">38</a> According to one of the seven rules in the compendium, a leap month should be added when the Pleiades appear next to a crescent moon a few days old in the spring, as depicted on the disc. This conjunction occurs approximately every three years.<a class="footnote-ref" id="fnref:39" href="#fn:39">39</a><a class="footnote-ref" id="fnref:40" href="#fn:40">40</a><a class="footnote-ref" id="fnref:41" href="#fn:41">41</a> 
Harald Meller suggests that knowledge of this rule may have come from Babylonia to Central Europe through long-distance trade and contacts, despite it being attested earlier on the Nebra disc than in Babylonia.<a class="footnote-ref" id="fnref:42" href="#fn:42">42</a> <a href="/facts/Baltic_amber/nHdQQKw7">Baltic amber</a> beads have been found in a foundational deposit under the large <a href="/facts/Ziggurat/5aB99m7n">ziggurat</a> of <a href="/facts/A%C5%A1%C5%A1ur/trEQvzpD">Aššur</a> in <a href="/facts/Iraq/pqYSFJw8">Iraq</a> dating from c. 1800-1750 BC, indicating that a connection existed between both regions when the Nebra disc was created.<a class="footnote-ref" id="fnref:43" href="#fn:43">43</a> However some Assyriologists and astronomers have rejected the comparison of the Nebra Disc with MUL.APIN.<a class="footnote-ref" id="fnref:44" href="#fn:44">44</a><a class="footnote-ref" id="fnref:45" href="#fn:45">45</a><a class="footnote-ref" id="fnref:46" href="#fn:46">46</a>

The number of stars depicted on the disc (32) is also thought to be significant, possibly encoding the calendar rule numerically. Firstly, the conjunction of lunar crescent and Pleiades depicted on the disc occurs after 32 days following the last "new light" (the first visible crescent moon of the month), and not before.<a class="footnote-ref" id="fnref:47" href="#fn:47">47</a> Secondly, because a <a href="/facts/Lunar_Year/llUN81gP">lunar year</a> (354 days) is eleven days shorter than a <a href="/facts/Solar_Year/ASBLWNMY">solar year</a> (365 days), 32 solar years is equal in length to 33 lunar years (with an error of only two days). That is, 32 x 365 = 11680 days, and 33 x 354 = 11682 days.<a class="footnote-ref" id="fnref:48" href="#fn:48">48</a> This 32 solar-year cycle may be represented on the disc by 32 stars, plus the sun (or full moon), adding up to 33.<a class="footnote-ref" id="fnref:49" href="#fn:49">49</a><a class="footnote-ref" id="fnref:50" href="#fn:50">50</a>
The archaeologist Christoph Sommerfeld has argued that the disc encodes knowledge of the 19-year lunisolar <a href="/facts/Metonic_cycle/8souG9fM">Metonic cycle</a>.<a class="footnote-ref" id="fnref:51" href="#fn:51">51</a> According to Sommerfeld the Metonic cycle is similarly encoded on the disc of the <a href="/facts/Trundholm_sun_chariot/zCvCy0mK">Trundholm sun chariot</a>, dating from c. 1500 BC.<a class="footnote-ref" id="fnref:52" href="#fn:52">52</a> The Metonic cycle is also thought to be encoded on the Late Bronze Age <a href="/facts/Golden_hat/ajxt1GeN">Berlin Gold Hat</a>, which features a band of 19 "<a href="/facts/Star_and_crescent/A5SaPECh">star and crescent</a>" symbols.<a class="footnote-ref" id="fnref:53" href="#fn:53">53</a>
Some authors have argued that the number of pin holes around the rim of the disc (approximately 38 to 40) has an astronomical significance. The exact number is not known due to damage to the disc.<a class="footnote-ref" id="fnref:54" href="#fn:54">54</a><a class="footnote-ref" id="fnref:55" href="#fn:55">55</a>
The Nebra Disc has been compared to a passage from the Greek poet <a href="/facts/Hesiod/3H9u3g7n">Hesiod</a>, written around 700 BC, which describes the role of the Pleiades for organizing the agricultural year:

"When the Pleiades, daughters of Atlas, are rising, begin your harvest, and your ploughing when they are going to set. Forty nights and days they are hidden and appear again as the year moves round, when first you sharpen your sickle. This is the law of the plains, and of those who live near the sea, and who inhabit rich country, the glens and hollows far from the tossing sea,—strip to sow and strip to plough and strip to reap, if you wish to get in all Demeter's fruits in due season, and that each kind may grow in its season."<a class="footnote-ref" id="fnref:56" href="#fn:56">56</a><a class="footnote-ref" id="fnref:57" href="#fn:57">57</a>

Depictions of the Pleiades are also known from some rock carvings dating from the early Bronze Age, such as at <a href="/facts/Mont_B%C3%A9go/LWRX6Epk">Mont Bégo</a> in the <a href="/facts/Vall%C3%A9e_des_merveilles/AfpzoXAs">southern Alps</a><a class="footnote-ref" id="fnref:58" href="#fn:58">58</a><a class="footnote-ref" id="fnref:59" href="#fn:59">59</a> and on the 'Calendar Stone' at Leodagger in Austria, a cult site associated with the <a href="/facts/%C3%9An%C4%9Btice_culture/t7jhmI9r">Únětice culture</a> which may have functioned as a calendar.<a class="footnote-ref" id="fnref:60" href="#fn:60">60</a><a class="footnote-ref" id="fnref:61" href="#fn:61">61</a> The Nebra Disc has some similarities to petroglyphs from the <a href="/facts/Nordic_Bronze_Age/x3e8bnrB">Nordic Bronze Age</a>, some of which are thought to have a calendrical meaning.<a class="footnote-ref" id="fnref:62" href="#fn:62">62</a><a class="footnote-ref" id="fnref:63" href="#fn:63">63</a><a class="footnote-ref" id="fnref:64" href="#fn:64">64</a>

<h3>Mythology</h3>

A depiction of a sun and crescent moon similar to the Nebra disc appears on a gold signet ring from <a href="/facts/Mycenae/FXGtmBkF">Mycenae</a> in Greece, dating from the fifteenth century BC.<a class="footnote-ref" id="fnref:65" href="#fn:65">65</a><a class="footnote-ref" id="fnref:66" href="#fn:66">66</a><a class="footnote-ref" id="fnref:67" href="#fn:67">67</a> Beneath the sun and moon is a seated female figure holding three <a href="/facts/Papaver_somniferum/C3qaRQYw">opium poppies</a> in her hand, identified as a goddess of nature and fertility, possibly the Minoan <a href="/facts/Poppy_goddess/qkn8ERgf">poppy goddess</a>, or an early form of the goddess <a href="/facts/Demeter/msJN4G3H">Demeter</a>.<a class="footnote-ref" id="fnref:68" href="#fn:68">68</a><a class="footnote-ref" id="fnref:69" href="#fn:69">69</a><a class="footnote-ref" id="fnref:70" href="#fn:70">70</a><a class="footnote-ref" id="fnref:71" href="#fn:71">71</a> The gold arcs on the Nebra disc also bear a resemblance to the <a href="/facts/Labrys/cMfuApth">Minoan double-axe</a> or labrys, which is centrally depicted on the gold signet ring and considered to be the main symbol of the Minoan goddess, as well as a symbol of Demeter.<a class="footnote-ref" id="fnref:72" href="#fn:72">72</a><a class="footnote-ref" id="fnref:73" href="#fn:73">73</a><a class="footnote-ref" id="fnref:74" href="#fn:74">74</a> According to the archaeologist <a href="/facts/Kristian_Kristiansen_(archaeologist)/GW5FYT8C">Kristian Kristiansen</a>, imagery similar to that found on Mycenaean signet rings appears in <a href="/facts/Nordic_Bronze_Age/x3e8bnrB">Nordic Bronze Age</a> petroglyphs from the <a href="/facts/The_King%27s_Grave/qmy0ESbc">Kivik King's Grave</a> in Sweden, dating from the 16th to 15th centuries BC, whilst Baltic amber has been found in the elite <a href="/facts/Grave_Circle_A,_Mycenae/WBCG9rtu">shaft graves</a> at Mycenae.<a class="footnote-ref" id="fnref:75" href="#fn:75">75</a><a class="footnote-ref" id="fnref:76" href="#fn:76">76</a> Opium poppy has also been found in settlements of the Únětice culture where it may have been used in cult rituals.<a class="footnote-ref" id="fnref:77" href="#fn:77">77</a>

<h4>Solar boat</h4>
The gold arc at the bottom of the Disc is usually interpreted as a mythological <a href="/facts/Solar_deity/Q2CS3IHN">solar boat</a> or sun-ship, which carried the sun through the day and night.<a class="footnote-ref" id="fnref:78" href="#fn:78">78</a> The short lines on each side of the gold arc may represent the oars of a large crew.<a class="footnote-ref" id="fnref:79" href="#fn:79">79</a> According to the archaeologist Harald Meller this imagery was "hitherto unknown in Europe" and probably originated in <a href="/facts/Ancient_Egypt/BDsEGK4g">Egypt</a>, possibly reaching Central Europe through wide-ranging contacts and travel.<a class="footnote-ref" id="fnref:80" href="#fn:80">80</a> In contrast the archaeologist Mary Cahill has argued that sun-ships were already depicted on <a href="/facts/Gold_lunula/zm21t6lw">gold lunulae</a> from the <a href="/facts/Bell_Beaker_culture/agsDNprM">Bell Beaker culture</a>, from which the Únětice culture developed.<a class="footnote-ref" id="fnref:81" href="#fn:81">81</a> Solar boats may even be depicted on rock art from the Neolithic or earlier.<a class="footnote-ref" id="fnref:82" href="#fn:82">82</a><a class="footnote-ref" id="fnref:83" href="#fn:83">83</a> 
Solar boats or vessels also appear in later <a href="/facts/Proto-Indo-European_mythology/je34oLVn">Indo-European</a> traditions: in <a href="/facts/Latvians/pft8pGHA">Latvian</a> folk songs the sun goddess <a href="/facts/Saul%C4%97/K39sc8aG">Saulė</a> sleeps through the night in a golden boat, whilst in the <a href="/facts/Atharvaveda/21Nq9UIk">Atharvaveda</a> the Sun is twice told ‘O Aditya, thou hast boarded a ship of a hundred oars for well-being’.<a class="footnote-ref" id="fnref:84" href="#fn:84">84</a> In <a href="/facts/Greek_mythology/M7k4FvW8">Greek mythology</a> the Sun's vessel takes the form of a golden bowl or cup, which may resemble the bowl-like shape of the Nebra boat.<a class="footnote-ref" id="fnref:85" href="#fn:85">85</a><a class="footnote-ref" id="fnref:86" href="#fn:86">86</a> Similar artefacts from the Bronze Age include the ship-like <a href="/facts/Caergwrle_Bowl/GozIEXFY">Caergwrle bowl</a> from Wales<a class="footnote-ref" id="fnref:87" href="#fn:87">87</a> and minature gold boats from Nors in Denmark.<a class="footnote-ref" id="fnref:88" href="#fn:88">88</a> Gold bowls from the later Bronze Age such as from the <a href="/facts/Eberswalde_Hoard/AfafyHWm">Eberswalde Hoard</a> in Germany feature circular solar symbols, and some of these may contain calendrical information, including the equivalence of 32 solar and 33 lunar years possibly depicted on the Nebra Disc.<a class="footnote-ref" id="fnref:89" href="#fn:89">89</a><a class="footnote-ref" id="fnref:90" href="#fn:90">90</a>
Numerous depictions of solar boats are known from the Nordic Bronze Age, dating from c. 1600 BC onwards.<a class="footnote-ref" id="fnref:91" href="#fn:91">91</a> Many of these are flat-bottomed vessels but some have a curved shape similar to the Nebra boat. Some of these depictions show people performing backward bends or backward leaps over ships, which the archaeologist Rune Iversen has connected to similar depictions from Egypt, which show backward-bend dances performed during festivals for the goddess <a href="/facts/Hathor/WS0VMr1j">Hathor</a>.<a class="footnote-ref" id="fnref:92" href="#fn:92">92</a> They may also be related to a later account from the <a href="/facts/Roman_Empire/l4E1aUuV">Roman</a> historian <a href="/facts/Tacitus/u6m0E441">Tacitus</a>, who stated that the Germanic <a href="/facts/Suebi/dg0NkYWh">Suebi</a> worshipped the goddess <a href="/facts/%22Isis%22_of_the_Suebi/zSPVtghX">Isis</a> in the form of a ship.<a class="footnote-ref" id="fnref:93" href="#fn:93">93</a> Isis was equated with Hathor from the <a href="/facts/New_Kingdom_of_Egypt/8cpKbCI0">New Kingdom</a> onwards, and both goddesses were associated with the <a href="/facts/Solar_barque/Vqhw7BHA">solar barque</a>, often being depicted at the <a href="/facts/Bow_(watercraft)/7IMvUGon">prow</a> of the ship, which they steered and protected.<a class="footnote-ref" id="fnref:94" href="#fn:94">94</a><a class="footnote-ref" id="fnref:95" href="#fn:95">95</a> Both were also associated with the goddess Demeter by the later Greeks.<a class="footnote-ref" id="fnref:96" href="#fn:96">96</a>
The historians Joseph S. Hopkins and Haukur Þorgeirsson have connected Tacitus' 'Isis of the Suebi' with the <a href="/facts/Norse_mythology/hEKfeQql">Norse</a> goddess <a href="/facts/Freyja/M087RW40">Freyja</a>, arguing for a strong association between Freyja and ship imagery within <a href="/facts/Old_Norse/3dIvgsm5">Old Norse</a> texts, and particularly with the <a href="/facts/Stone_ship/0bkQKuQs">stone ships</a> of Scandinavia.<a class="footnote-ref" id="fnref:97" href="#fn:97">97</a><a class="footnote-ref" id="fnref:98" href="#fn:98">98</a> Both Freyja and her twin brother Freyr have characteristics associated with solar gods,<a class="footnote-ref" id="fnref:99" href="#fn:99">99</a> including the golden ship <a href="/facts/Sk%C3%AD%C3%B0bla%C3%B0nir/WXx3WrzC">Skíðblaðnir</a> belonging to Freyr, which may represent a solar boat.<a class="footnote-ref" id="fnref:100" href="#fn:100">100</a> 

<h4>Divine Twins</h4>
According to Kristian Kristiansen the pairs of swords and axes deposited with the Nebra Disc represent the mythological <a href="/facts/Divine_twins/1IT380qQ">Divine Twins</a>, later known as the <a href="/facts/Dioscuri/SCBRfAr0">Dioscuri</a> in Greece and as the <a href="/facts/Ashvins/NV4YUlml">Ashvins</a> in India, among other Indo-European traditions.<a class="footnote-ref" id="fnref:101" href="#fn:101">101</a> Similar depositions are known from a number of other Bronze Age burials. Kristiansen further suggests that the constellation of <a href="/facts/Gemini_(constellation)/uTHx4pw9">Gemini</a>, which is associated with the Dioscuri, might be represented in the lower part of the Disc next to the solar boat.<a class="footnote-ref" id="fnref:102" href="#fn:102">102</a> The archeologist <a href="/facts/Timothy_Darvill/t8bKoJkU">Timothy Darvill</a> has suggested a connection between these paired depositions and the Nebra Disc with the <a href="/facts/Trilithon/kuzR6yUT">trilithons</a> at <a href="/facts/Stonehenge/5TDRUktP">Stonehenge</a>, which may also represent an early form of the Divine Twins.<a class="footnote-ref" id="fnref:103" href="#fn:103">103</a> The central trilithon in particular may have embodied "a pair of deities representing day and night, the sun and moon, summer and winter, life and death, perhaps even the prehistoric equivalents of the twins <a href="/facts/Apollo/eBJV1wsJ">Apollo</a> and <a href="/facts/Artemis/bocCzux6">Artemis</a> as they are known in later pantheons across the Old World."<a class="footnote-ref" id="fnref:104" href="#fn:104">104</a> In Greece Apollo and Artemis were associated with the sun and the moon respectively, whilst the Pleiades were known as '<a href="/facts/Pleiades_(Greek_mythology)/77uExCU0">the companions of Artemis</a>', echoing the depiction on the Nebra Disc.<a class="footnote-ref" id="fnref:105" href="#fn:105">105</a> According an account recorded by the Greek historian <a href="/facts/Herodotus/hTgRSAnv">Herodotus</a>, the Egyptians maintained that Apollo and Artemis were the children of Isis, equivalent to the gods <a href="/facts/Horus/yPPMRMGn">Horus</a> and <a href="/facts/Bastet/HncBq316">Bubastis</a>, and that Isis was Demeter.<a class="footnote-ref" id="fnref:106" href="#fn:106">106</a> 

<h3>Connections with Britain</h3>
Archaeoastronomist Emília Pásztor has argued against a practical astronomical function for the disc. According to Pásztor "the close agreement of the length of the peripheral arcs with the movement of the sun's risings or settings might be a pure coincidence".<a class="footnote-ref" id="fnref:107" href="#fn:107">107</a> This claim is undermined by the finding of a similar feature on the roughly contemporary gold lozenge from <a href="/facts/Bush_Barrow/RGHBxqny">Bush Barrow</a> at <a href="/facts/Stonehenge/5TDRUktP">Stonehenge</a>, where the acute angles of the overall design (81°) correspond to the angle between the solstices at the latitude of Stonehenge.<a class="footnote-ref" id="fnref:108" href="#fn:108">108</a><a class="footnote-ref" id="fnref:109" href="#fn:109">109</a> According to <a href="/facts/Euan_MacKie/TwL9VGze">Euan MacKie</a> (2009) "The Nebra disc and the Bush Barrow lozenge both seem to be designed to reflect the annual solar cycle at about latitude 51° north."<a class="footnote-ref" id="fnref:110" href="#fn:110">110</a> 
MacKie further suggests that both the Nebra disc and Bush Barrow lozenge may be linked to the solar calendar reconstructed by <a href="/facts/Alexander_Thom/8AXwEg1S">Alexander Thom</a> from his analysis of standing stone alignments in Britain.<a class="footnote-ref" id="fnref:111" href="#fn:111">111</a> Both the Nebra sky disc and Bush Barrow lozenge were made with gold from <a href="/facts/Bronze_Age_Cornwall/TEfxluwl">Cornwall</a>, providing a direct link between them.<a class="footnote-ref" id="fnref:112" href="#fn:112">112</a><a class="footnote-ref" id="fnref:113" href="#fn:113">113</a> According to the archaeologist Sabine Gerloff the gold plating technique used on the Nebra sky disc also originated in Britain, and was introduced from there to the continent.<a class="footnote-ref" id="fnref:114" href="#fn:114">114</a>

<h2 id="authenticity">Authenticity</h2>
There were some initial suspicions that the disc might be an <a href="/facts/Archaeological_forgery/xSD4EmTN">archaeological forgery</a>. Peter Schauer of the University of Regensburg, Germany, argued in 2005 that the Nebra disc was a fake and that he could prove that the patina of the disc could have been created with urine, <a href="/facts/Hydrochloric_acid/HqItJlUT">hydrochloric acid</a>, and a blow torch within a short amount of time. He had to admit in court that he had never held the disc in his own hands, unlike the eighteen scientists who had examined the disc.<a class="footnote-ref" id="fnref:115" href="#fn:115">115</a> Scientific analyses of the patina (or corrosion layer) have confirmed its authenticity.<a class="footnote-ref" id="fnref:116" href="#fn:116">116</a>
Richard Harrison, professor of European prehistory at the <a href="/facts/University_of_Bristol/naU7Gvlc">University of Bristol</a>, stated in a <a href="/facts/BBC/qFateIz8">BBC</a> documentary that "When I first heard about the Nebra Disc I thought it was a joke, indeed I thought it was a forgery", due to the extraordinary nature of the find, although he had not seen the sky disc at the time. The same documentary presented scientific analyses confirming the authenticity of the disc.<a class="footnote-ref" id="fnref:117" href="#fn:117">117</a>
A paper published in 2020 by Rupert Gebhard and Rudiger Krause questioned the Early Bronze Age dating of the Nebra disc and proposed a later Iron Age date instead.<a class="footnote-ref" id="fnref:118" href="#fn:118">118</a> A response paper was published in the same year by Ernst Pernicka and colleagues, rejecting the arguments of Gebhard and Krause.<a class="footnote-ref" id="fnref:119" href="#fn:119">119</a> Scientific analyses of the disc, the items found with the disc, and the find spot have all confirmed the Early Bronze Age dating.<a class="footnote-ref" id="fnref:120" href="#fn:120">120</a><a class="footnote-ref" id="fnref:121" href="#fn:121">121</a>

<h2 id="exhibition">Exhibition</h2>
The disc was the centre of an exhibition entitled Der geschmiedete Himmel (German "The forged sky"), showing 1,600 Bronze Age artefacts, including the <a href="/facts/Trundholm_sun_chariot/zCvCy0mK">Trundholm sun chariot</a>, shown at <a href="/facts/Halle_(Saale)/hJ3EBuMn">Halle</a> from 15 October 2004 to 22 May 2005, from 1 July to 22 October 2005 in <a href="/facts/Copenhagen/58Tl28IX">Copenhagen</a>, from 9 November 2005 to 5 February 2006 in <a href="/facts/Vienna/NSpIURsA">Vienna</a>, from 10 March to 16 July 2006 in <a href="/facts/Mannheim/f5GsdPcG">Mannheim</a>, and from 29 September 2006 to 25 February 2007 in <a href="/facts/Basel/EzXbzbUx">Basel</a>.
On 21 June 2007, a multimedia visitor centre was opened near the discovery site at Nebra.<a class="footnote-ref" id="fnref:122" href="#fn:122">122</a>
The disc is part of the permanent exhibition in the <a href="/facts/Halle_State_Museum_of_Prehistory/vJM5ojpg">Halle State Museum of Prehistory</a> (Landesmuseum für Vorgeschichte) in <a href="/facts/Halle_(Saale)/hJ3EBuMn">Halle</a>.
The disc was on display at the <a href="/facts/British_Museum/mq5LadWV">British Museum</a> in London as part of The World Of Stonehenge Exhibition from 17 February to 17 July 2022.<a class="footnote-ref" id="fnref:123" href="#fn:123">123</a> The disc was on display at the <a href="/facts/Drents_Museum/k4rQhe19">Drents Museum</a> in Assen from 6 August to 18 September 2022.<a class="footnote-ref" id="fnref:124" href="#fn:124">124</a>

<h2 id="replica-on-the-iss">Replica on the ISS</h2>
In November 2021, a replica of the Nebra Sky Disc was launched to the <a href="/facts/International_Space_Station/VNPUBz9m">International Space Station</a> on the <a href="/facts/SpaceX_Crew-3/YLx0SWlU">Crew-3</a> mission, taken by German astronaut <a href="/facts/Matthias_Maurer/LvB5CDzN">Matthias Maurer</a>. Maurer, who was part of the European mission Cosmic Kiss, designed the mission's patch with inspiration from the Nebra Sky Disk, as well as the Pioneer plaques and Voyager Golden Records that were sent into the unknown carrying messages from Earth.<a class="footnote-ref" id="fnref:125" href="#fn:125">125</a>

<h2 id="legal-issues">Legal issues</h2>

The <a href="/facts/States_of_Germany/hIpruCeX">state</a> of <a href="/facts/Saxony-Anhalt/XWDDbRvA">Saxony-Anhalt</a> registered the disc as a <a href="/facts/Trademark/B23H8IS0">trademark</a>, which resulted in two lawsuits. In 2003, Saxony-Anhalt successfully sued the city of <a href="/facts/Querfurt/U5ehXGkl">Querfurt</a> for depicting the disc design on souvenirs. Saxony-Anhalt also successfully sued the publishing houses <a href="/facts/Piper_Verlag/6wExVwJD">Piper</a> and Heyne over an abstract depiction of the disc on book covers.<a class="footnote-ref" id="fnref:126" href="#fn:126">126</a> The <a href="/facts/Magdeburg/8SW8I5NB">Magdeburg</a> court assessed the case's relevance according to <a href="/facts/German_copyright_law/0Q90mdPF">German copyright law</a>. 
The defenders argued that as a cult object, the disc had already been "published" approximately 3,500 years earlier in the Bronze Age and that consequently, all protection of <a href="/facts/Intellectual_property/PqHW9mVP">intellectual property</a> associated with it has long expired. The plaintiff, on the other hand, argued that the <a href="/facts/Editio_princeps/8UgyQJqm">editio princeps</a> of the disc is recent, and according to German law protected for 25 years, until 2027. Another argument concerned the question of whether a notable work of art may be registered as a trademark in the first place. The Magdeburg court decided in favour of the State of Saxony-Anhalt.
The case was appealed and on the basis of decisions from the <a href="/facts/Oberlandesgericht/Aytpzjwr">Oberlandesgericht</a> <a href="/facts/D%C3%BCsseldorf/twteRHCh">Düsseldorf</a> in 2005 and the <a href="/facts/Federal_Court_of_Justice/w8bUeflr">Federal Court of Justice</a> in 2009, the initial ruling was overturned and the German Patent and Trademark Office withdrew the trademark rights.<a class="footnote-ref" id="fnref:127" href="#fn:127">127</a> Thereafter, the state of Saxony-Anhalt registered the design of the disc as a trademark with the European Union Intellectual Property Office.<a class="footnote-ref" id="fnref:128" href="#fn:128">128</a>
In 2023, the state of Saxony-Anhalt filed a <a href="/facts/Digital_Millennium_Copyright_Act/rVTdnnc2">DMCA</a> <a href="/facts/Notice_and_take_down/7qwAKKuW">take down notice</a> requesting removal of nine images of the Nebra sky disc from <a href="/facts/Wikimedia_Commons/lzkBFxTg">Wikimedia Commons</a>, asserting that they were the "owner of the exclusive copyright in the Sky Disk of Nebra".<a class="footnote-ref" id="fnref:129" href="#fn:129">129</a> <a href="/facts/Wikimedia_Deutschland/0tdyXotI">Wikimedia Deutschland</a>, a chapter of the <a href="/facts/Wikimedia_Foundation/W1XHdpK2">Wikimedia Foundation</a>, subsequently filed a DMCA counter-notice stating that since the implementation of <a href="/facts/Directive_on_Copyright_in_the_Digital_Single_Market/nEBbpxUc">Article 14 of the Directive 2019/790 of the European Parliament</a>, there can be no such copyrights on reproductions of visual works that are in the public domain.<a class="footnote-ref" id="fnref:130" href="#fn:130">130</a>

<li id="fn:37">"The Nebra Sky Disc". Archaeology. June 2019. In the first phase, the disc showed the night sky with 32 gold stars, including the Pleiades, a gold orb representing the sun or a full moon, and a crescent moon. It served as a reminder of when it was necessary to synchronize the lunar and solar years by inserting a leap month. This phenomenon occurred when the three-and-a-half-day-old moon—the crescent moon on the disc—was visible at the same time as the Pleiades. 'The astronomical rules that are depicted wouldn't be imaginable without decades of intensive observation,' says Harald Meller, director of the State Museum for Prehistory in Halle. 'Until the Sky Disc was discovered, no one thought prehistoric people capable of such precise astronomical knowledge.' <a href="https://www.archaeology.org/issues/338-features/maps/7543-maps-germany-nebra-sky-disc" target="_blank">https://www.archaeology.org/issues/338-features/maps/7543-maps-germany-nebra-sky-disc</a> <a href="#fnref:37" class="footnote-back-ref">↩</a></li>

(on the disc) there is a distinctive rosette of seven stars clustered between the full and crescent moons. These are identified as the Pleiades or Seven Sisters, recognised by many world cultures as calendar stars, since they are last seen in the night sky in March and only reappear again in October. ... The path of the sun provides a measure of the time of day and year, while the moon can do the same in measuring out months and weeks based on its regular cycles. A problem arises, however, when it comes to equating the solar and lunar years. The former is eleven days longer than the later and after three years the difference is equivalent to about a month. To bring the two calendars into harmony a rule is needed. The first written record of such a rule comes from a Babylonian cuneiform tablet dating to the seventh or sixth centuries BC, which advises to add a leap month every third year if no new moon appears next to the Pleiades in the spring but rather a crescent moon a few days old. That arrangement of heavenly bodies is precisely what the Sky Disc seems to show, reflecting an ingenious materialisation of a complex astronomical and calendrical rule without the need for writing. <a href="9780714123493" target="_blank">9780714123493</a> <a href="#fnref:39" class="footnote-back-ref">↩</a></li>

The synchronisation key of the first phase [of the Nebra disc] allowed the longer solar year (approximately 365 days) to be harmonised with the shorter lunar year (around 354 days). Each year in spring, the crescent moon passed close to the Pleiades, appearing with different widths, depending on the lunar phase. The appearance of a 4.5 day-old crescent moon next to the Pleiades, as shown on the Sky Disc, meant that an extra month should have been added, since the solar and lunar years differed by approximately one month after every three years. <a href="978-3-948618-22-3" target="_blank">978-3-948618-22-3</a> <a href="#fnref:40" class="footnote-back-ref">↩</a></li>

Zudem vergehen bei einer 4,5 Tage alten Mondsichel nicht wie üblich 29 oder 30 Tage seit dem letzten Neulicht, sondern 32 Tage. Dies korrespondiert mit den 32 Sternen, die auf der Himmelsscheibe in der ersten Phase abgebildet waren, sodass die Schaltregel wohl sogar doppelt verschlüsselt in diesem auf den ersten Blick simplen Bildwerk dargestellt ist. Das große runde Goldobjekt könnte zugleich Vollmond und Sonne repräsentieren. Die 32 Sterne der ersten Phase verkörpern dann 32 Sonnenjahre, denen – zählt man Vollmond / Sonne hinzu – 33 Mondjahre entsprechen (Hansen 2007). English translation: "with a 4.5-day old crescent moon, not 29 or 30 days elapse since the last new light, as is usually the case, but 32 days. This corresponds with the 32 stars that were depicted on the sky disc in the first phase, so that the leap rule is probably even depicted in a doubly coded way in this, at first sight, simple pictorial work.

Their disappearance and appearance has been seen historically as a marker of the beginning and end of the farming year in Europe [...] In the region of Germany where the disc was found, the Pleiades is last seen in the sky on 10 March, alongside the young, crescent moon. The full moon accompanies the reappearance of the constellation on 17 October. On the disc, the Pleiades is tellingly placed between the crescent and full moons, suggesting an awareness of this celestial rhythm. <a href="9780714123493" target="_blank">9780714123493</a> <a href="#fnref:57" class="footnote-back-ref">↩</a></li>

She is represented as a large female figurine with raised hands in a gesture of greeting or blessing. [...] A goddess with the same emblems — three poppies — in her hand is depicted also in a gold signet ring from Mycenae. [...] The role of this goddess was correlated together with her attributes — poppies and its effects in a form of opium. [...] The motif of a seated goddess (who was called Demeter) on a throne with poppies in her hand is found on a Greek vase (plate) of the fifth century BCE. There is presently not enough evidence to connect a real name to this so-called Poppy Goddess of the pre-Hellenic period; nevertheless there are links to the Greek pantheon and to a ritual performed, later in honor of the goddess Demeter. <a href="#fnref:69" class="footnote-back-ref">↩</a></li>

The potential observation of the horizon arc described by the Sun during its annual motion is exemplified by another impressive find from the Early Bronze Age: A diamond-shaped gold plaque of extraordinary quality was excavated in a burial under Bush Barrow in Wiltshire, southern England, less than a mile away from Stonehenge. ... Both objects, the Nebra Sky Disc and the Bush Barrow Lozenge, are unique in their appearance, but they may be related in their ritual and possibly astronomical relevance. <a href="https://doi.org/10.1080%2F1751696X.2018.1433358" target="_blank">https://doi.org/10.1080%2F1751696X.2018.1433358</a> <a href="#fnref:109" class="footnote-back-ref">↩</a></li>

S2CID 162360353. Ker and his colleagues found the pair of acute angles of the basic diamond pattern [of the Bush Barrow lozenge] to be 81°. They realized that this was the angle between midsummer and midwinter sunrises (and sunsets of course) on a low horizon at the latitude of Stonehenge (51.17° N) four thousand years ago. ... The Nebra disc and the Bush Barrow lozenge both seem to be designed to reflect the annual solar cycle at about latitude 51° north, and both have elements in their design which could refer specifically to the solar calendar. <a href="https://www.academia.edu/10771931" target="_blank">https://www.academia.edu/10771931</a> <a href="#fnref:110" class="footnote-back-ref">↩</a></li>

This phase also includes the hoard of Nebra with its famous disc showing gold-plated heavenly bodies. Its plating technique is generally connected to Mycenaean metalwork. It will be shown, however, that this technique together with that of metal inlay had its origins in Britain, where it was already applied to organic material during the first phase of the Early Bronze Age, and flourished during the second and third phases when it was introduced on the continent and used on prestige metalwork. <a href="978-3-939414-28-5" target="_blank">978-3-939414-28-5</a> <a href="#fnref:114" class="footnote-back-ref">↩</a></li>
