Tascheter--the spirit ruling the waters--found water for thirty days and thirty nights upon the earth. Every water-drop was as big as a bowl! (sic). The earth was covered with water the height of a man. All idolaters died through the rain; it penetrated all openings. Afterwards a wind from heaven divided the water, and carried it away in clouds, as souls bear bodies; then Ormuzd collected all the water together, and placed it as a boundary to the earth, and thus was the great ocean formed. http://www.antipope.org/feorag/wells/hope/introduction.html
