The Murano Diptych at the National Museum of Ravenna is a 6th century ivory diptych presenting themes popular in Christian art of the late classical period, mostly themes related to resurrection and the baptism that prefigures it. In the center Christ sits enthroned under a canopy, as in images of the emperor, surrounded by his "court" of evangelists.  On the left, he heals the blind man in the upper panel and the Gadarene demoniac in chains (Mark 5:1-15) in the lower one.  On the right, the upper image has the raising of Lazarus (John 11:1-45) while in the lower one the crippled man picks up his bed and walks (Mark 2:1-12, Luke 5:18-25, Matthew 9:2-7). 
The bottom tells the story of Jonah: On the right he is thrown into the sea, where the sea monster awaits with open mouth. On the left the monster has deposited him and he is sleeping under the gourd tree (Jonah 4:6-12) at the command of God, who is represented by an angel.
Beneath the central panel of Christ we also see the three men in the fiery furnace with the angel (Daniel 3).
