Most sarcophagi are of the well-known Lycian type with a rectangular coffin, but in Sidyma they have a hipped roof, rather than the saddle-shaped ("gothic vaulted") one as in many other Lycian cemeteries.
This unusual twin tomb belonged, as its inscription tells us, to a father and Son, both named Aristodemos. One was a court physician and honoured by the Roman Emperor.
The tomb right next to it is a temple-like tomb. It stands on a high podium and originally must have had two columns "in antis" (the portruding roof in front was supported by two columns). It has an elaborately decorated coffered ceiling, consisting of a huge slab decorated with heads and flowers inside square sunken panels of coffers (also called lacundaria or cassettes). One rosette still shows traces of colouring.
