The Nabataean script is an abjad (consonantal alphabet) that was used to write Nabataean Aramaic and Nabataean Arabic from the second century BC onwards. Important inscriptions are found in Petra (in Jordan), the Sinai Peninsula (now part of Egypt), Bosra and Namara (in Syria), and other archaeological sites including Abdah (in Israel) and Mada'in Saleh (Hegra) (in Saudi Arabia).
Nabataean is only known through inscriptions and, more recently, a small number of papyri. It was first deciphered in 1840 by Eduard Friedrich Ferdinand Beer. 6,000 – 7,000 Nabataean inscriptions have been published, of which more than 95% are extremely short inscriptions or graffiti, and the vast majority are undated, post-Nabataean or from outside the core Nabataean territory. A majority of inscriptions considered Nabataean were found in Sinai, and another 4,000 – 7,000 such Sinaitic inscriptions remain unpublished. Prior to the publication of Nabataean papyri, the only substantial corpus of detailed Nabataean text were the 38 funerary inscriptions from Mada'in Salih (Hegra), discovered and published by Charles Montagu Doughty, Charles Huber, Philippe Berger and Julius Euting in 1884-85.
