Ad-Deir (Monastery)

Petra, Jordan

The central tholos of ad-Deir rests between two half-pediments. It is framed by columns with Nabataean "horned capitals," and surmounted by a distinctive, urn-shaped finial. A continuous frieze links the tholos and pediments. Its design is a simple band of alternating triglyphs and disks (compare: frieze of a votive niche in the Siq).
