[1][2] The facade is shaped like that of a Greek temple, with four engaged Ionic columns supporting an architrave and a pediment.
The metre-high triangular tympanum is painted with a depiction of an old man and woman, who are presumably the tomb's occupants, lying together on a couch at a symposium.
The man lies on the left, wearing a white chiton and a red himation with a purple border.
He has a grey beard and holds a temple key in his right hand, probably indicating that he held a religious office.
The unique painted design on the ceiling, consisting of six palmettes and water lilies on a light blue background, is the source of the tomb's modern name.
