Apse Mosaic: Left Side
Detail of apse mosaic in Santi Cosma e Damiano, which dates from the church's foundation in 527 AD. It centers on the Second Coming of Christ. On Christ's right (our left), St. Paul introduces Cosmas or Damian, who is holding a martyr's crown. On the far left is Pope Felix IV (526-30), who offers Christ a model of the church he founded.
