It was made of Gopherwood. Unfortunately no one knows what Gopherwood is.
genesis 6 says it was made of ×¢Ö²×¦Öµ×™-×’Ö¹×¤Ö¶×¨ (etsi-gofer) or "gofer wood." most of the rest of the verse describes how noah is to cover the wood with pitch, or ×›Ö¼Ö¹×¤Ö¶×¨ (kofer). ×’Ö¹×¤Ö¶×¨ is probably a scribal error for ×›Ö¼Ö¹×¤Ö¶×¨. if you don't make the horizontal parts of a kaf long enough, it looks a little like a gimel.
interesting. Are you saying that you think it likely that "gofer" is a misreading of bad handwriting and that the original said it was to be made of "pitch wood" meaning I suppose wood with a lot of pitch in it?
pitched wood, yes. it's a somewhat common explanation, actually. i'd like to see the inerrentists come up with something better. :D
