Stairway to Heaven

When people visit Rome they focus on the ancient pagan-era monuments, but for me the Early Christian mosaics in churches such as San Clemente, Santa Pudenziana, and San Prasede, among others, are real treats. This is a detail of the vast mosaic program in the apse of San Prasede, showing the elect being greeted at the gates of heaven by an angel, all carrying the crowns of salvation.
