The Apsidal Arch at Santa Maria Maggiore: Right Side
Basilica of Santa Maria Maggiore, Rome
In the top register we see the Presentation in the Temple on the left and on the right the dream in which St. Joseph is warned to take the child into Egypt.
The second register is usually taken to represent the story in The Gospel of Pseudo-Matthew in which the family is welcomed by Aphrodisius, the governor of the Egyptian city of Sotinen.
In the third register the Magi consult with King Herod. This corresponds to a mosaic of the Epiphany on the left side.
The bottom register represents the town of Bethlehem.
