The Sarcophagus of the ChildChild-size sarcophagus from the Catacombs of Saint Callixtus
Left to right: Daniel and the lions, the deceased in orant posture, the miracle at Cana, and Lazarus.
The man offering food to the right of Daniel is the prophet Habakkuk. The story of Daniel in the lions' den is told not only in Daniel 6 (cached) but in a later chapter that appears only in the Greek text. In the latter, God sends Habakkuk to feed Daniel during his seven days in the den. See Vulgate Daniel 14:32-39 (cached).
