Bonaventure, on Gen 1:20

“God also said: Let the waters bring forth the creeping creature having life, and the fowl that may fly over the earth under the firmament of heaven.”

“The fifth vision, which comes about through understanding enlightened by prophecy, is still higher than the preceding ones, in that contingent things are seen infallibly, which comes about through a certain kind of sight looking into the Eternal Mirror. The contingent is changing and varied: if then a prophet sees with infallibility and certainty, everything he sees must be considered within infallible Truth. This vision is understood to refer to the fifth day when the fishes of the waters were made together with the birds, for the soul is carried up to God on the breeze by means of pinions and a great number of feathers.”
