The Day Five Window
The important act of separation on the fifth day of creation is between the creatures of the waters and the creatures of the air. Among the creatures of the water God creates the great sea-dragons, often found portrayed in other religious cultures as divine opponents of God, but here clearly under God’s dominion. God blesses the creatures of the seas and the birds of the firmament with fertility, to fill the world. Fertility is a central motif of this window, following the Torah passage which twice speaks of the waters “teeming” with life.
