The oldest instructions for building a coracle are on a 4000-year-old cuneiform clay tablet. This was dictated by the Mesopotamian god Enki to Atra-Hasis on how to build a round "ark". The tablet is about 2,250 years older than than the flood myths, none of which contain such details. The earliest known written evidence of a coracle-type boat (quffa), still in use today, is in the Bible, Exodus 2:3.
