Sarcophagi are a common form of burial all over the world, however Lycian sarcophagi are distinctive - especially for their great size. These sarcophagi usually consist of three parts: a base, a grave-chamber and a crested 'Gothic' (pointed) lid. In some sarcophagi deceased slaves and dependents were held in a hyposorion under the main grave-chamber. Lycian sarcophagi are often decorated with reliefs, usually on the sides and crest of the lid, but sometimes on the grave-chamber. Most of the intact Lycian sarcophagi belong to the Roman Age. These are generally smaller and simpler than those preceding them, though still with a crest and rounded lid. Some, however, have gable-shaped lids with acroteria at the lower corners (many of these can be seen at Sidyma). Most Lycian sarcophagi are free-standing, open to the sky, but others are placed inside of monumental tombs.
