The Flood
Rain from above and the deep from below, one ark on the water, a dove, and a bow in the cloud. Scroll to watch it.
And Moses showed that the flood lasted forty days and forty nights, torrents pouring from heaven, and from the fountains of the deep breaking up, so that the water overtopped every high hill 15 cubits.
Genesis 7:11-12, 17-20, as St Theophilus of Antioch gives it
he then sent forth a dove. It, not finding a place of rest, returned to him and being again sent out, it brought back an olive leaf, in manifest proof that the tops of the trees were now to be seen.
Genesis 8:8-12, as Sulpitius Severus gives it
And he, after having, as the flood was passing off, sent forth first a raven which did not return, sent forth a dove which is said to have returned with an olive twig. You see the water, you see the wood [of the ark], you see the dove, and do you hesitate as to the mystery?
