Among the figures of the fresco representations of Thera are some which are identified presumably as members of the priesthood. But it is rather difficult to distinguish the priests from the worshipers or possible illustrations of the deity since these representations do not seem to follow a strict religious ritual. Thus, the determination of the property of the figures results from the effort to interpret the ritual procedures and the often problematic classification of the figures in an iconographic program.

It is noteworthy that the female figures dominate in the religious scenes of Thera as in those of Minoan Crete. These figures are priestesses and maidservants of the goddess they praised, to whom they offered gifts, whereas there are specific ceremonies in which they represented her by incarnation. The priestesses wore extravagant Minoan style costumes. They had elaborate hair styles and sometimes tattoos of sacred symbols (e.g. crocus) on their face. A priestess from a West House fresco, holding a censer and wearing a long and large, sleeved garment probably represents a specific position in the religious hierarchy.

There are also certain male figures from the "Flotilla Fresco" in the scene of the ritual on the peak of a hill which are considered as members of the priesthood. These figures are illustrated with long white garments while those with the white Minoan type loincloths of the same scene represent perhaps the worshipers. Male figures wearing animal hides which suggest the similarly dressed priests of the sarcophagus of Agia Triada are also considered as members of the priesthood.
