The Hall of the Saints or the Sala dei Santi is a room in the Borgia Apartment of the Vatican Palace, frescoed by the Italian Renaissance artist, Pinturicchio.
The ceiling fresco, which depicts myths related to the ancient Egyptian gods Osiris and Isis, has been the subject of much scholarly attention.
[1] Using his position as Pope, Alexander VI wanted Pinturicchio's frescoes to help establish his legitimacy of claims in having Egyptian ancestry.
Located in the fourth room, there’s a fresco of the Visitation that contains the seven saints: Anthony, Barbara, Catherine, Elizabeth, Paul, Sebastian, and Susanna.
[2] The scenes that were inspired by the ancient Egyptian myths or in pagan culture are found the same decorations inside the Hall of Saints, specially centering on the presence of the bull.
Pope Alexander VI had shared a great fondness for the bull and included various imagery of the animal in a variety of media and scales portrayed throughout the Borgia Apartment.
Apis was considered by the Egyptians as a system of worship and the Borgia family’s insignia of a bull serves as a symbol of the Christian Church in its triumph.
This inscription further serves as a way to claim legitimacy to what Pope Alexander VI by stating that having supreme spiritual power mediates between earth and heaven.
These frescos were made to propagandize Pope Alexander VI, who wanted to show his divinely sanction as the head of the church.
The Hall of Saints illustration of the myth of Osiris and Apis provided both a historical and mythical justification for the Borgia family to claim as their ‘ancestral’ right to rule Italy, because of their ‘Egyptian’ ancestors.
[1] In Giovanni Annio of Viterbo's works of Diodorus Siculus, he talks about Isis and Osiris establishing colonies in the Mediterranean Sea, which he connects to the Borgia family's divine Egyptian ancestry.
