Το εορτολόγιο της εκκλησίας ως κύριος παράγων στην εικονογράφηση βυζαντινών ναών
This article deals with some groups of saints in the iconographic programs of Byzantine churches. The main criterion for their presentation is the church calendar, more specifically, the fact that they are commemorated collectively in the liturgy. This iconographic practice seems to have first come into use in the churches of Constantinople, where the collective celebration (synaxis) of multiple saints took place. The largest group of saints commemorated in this way is the Seventy Apostles.
