But the dove could find no place to perch, and it returned to him in the ark, for there was water over all the earth. Putting out his hand, he caught the dove and drew it back to him inside the ark. - Genesis 8
Then the pope released two doves to ask for peace. One remained on his window sill, while the other flew a few yards, but then returned to the safe refuge of the papal apartment... for there was conflict over all the earth.
