Geison

<p>Geison  is an <a href="/facts/List_of_classical_architecture_terms/jNYMoyCL">architectural term</a> of relevance particularly to ancient Greek and Roman buildings, as well as archaeological publications of the same.  The geison is the part of the <a href="/facts/Entablature/c4o7eDhy">entablature</a> that projects outward from the top of the frieze in the <a href="/facts/Doric_order/oDLVobAY">Doric order</a> and from the top of the frieze course (or sometimes <a href="/facts/Architrave/RwC27HKw">architrave</a>) of the <a href="/facts/Ionic_order/rG6Ajtkr">Ionic</a> and <a href="/facts/Corinthian_order/2zCzPuH4">Corinthian</a> orders; it forms the outer edge of the roof on the sides of a structure with a sloped roof.  The upper edge of the exterior often had a drip edge formed as a hawksbeak molding to shed water; there were also typically elaborate moldings or other decorative elements, sometimes painted.  Above the geison ran the <a href="/facts/Sima_(architecture)/We8FnbVv">sima</a>.  The underside of the geison may be referred to as a <a href="/facts/Soffit/sgqkdbzp">soffit</a>.  The form of a geison (particularly the Hawksbeak molding of the outer edge) is often used as one element of the argument for the chronology of its building.
