As the Sidamara is a type name, this is another one. Iznik, 2nd. Century AD.

The type-name ‘Sidamara’ refers to the name of a (small) ancient city of Lycaonia, near the modern village of Ambar, North of the Karaman-Ereğli road, about 35 km west of Ereğlı. An enormous Roman sarcophagus was found there in 1900 and brought to Istanbul by Osman Hamdi Bey (painter, ethnologist, archeologist and director of the Imperial Museum in Istanbul since 1881). Since then, the name ‘Sidamara’ is better known as a type-name for some large Roman sarcophagi as for the ancient town itself.
