Noah's Ark was a basket
The other day I watched a Nova program, Secrets of Noah’s Ark. Not much wholly new, and not a whole lot of secrets, but if you watch the program, you will learn of cuneiform inscriptions that describe how the gods precipitate a universal flood, Atrahasis builds an “ark” in the form of a circular basket 220 ft in diameter (70 m for those with better taste), and life begins again, precisely as in the Noah story. Or perhaps it is the other way around: the Jews during the Babylonian captivity took the story of Atrahasis and embellished it by making it a sort of morality play.
At any rate, if you watch the video, you will find that the Ark was more than likely a round, woven boat, known as a coracle, as in the picture above. Such boats are woven from reed ropes and sealed with pitch; they have been used for several millennia. The attempt to manufacture a coracle on a large scale was also interesting, even though it ended in only partial success.
Noah’s Ark is said to have been a rectangular box (Genesis 6:15). Doubtful. More than likely, the Ark was a coracle. It was not, at any rate, shaped the least bit like a certain model being built in Kentucky right now.
