They didn't have real knitting that early...nalbinding which looks like knitting, though, was done all over the ancient world...it's done with a single needle with an eye like a sewing needle and short sewing lengths of thread. The Romans made striped socks that look something like modern athletic socks with that technique. But you could do a lot more textures with nalbinding than with knitting.
The book sounds very interesting...
Fantastic book! Great photos of textiles, too.
Barber's other books, Women's Work: the First 2,000 Years is a great look at primitive spinning and Weaving. It is a popular cut down of her thesis book, Prehistoric Textiles.
Textile historians rock!
Knitting a Conundrum, I'm coming to the conclusion that circular needles aggravate my tendinitis (an old knitting injury lol), and I'm about to invest in a drawer full of longer and larger dp needles. The vision of you working on your hat is soothing, but then, I'm warped. (About to fire up the cd burner, thanks for your patience.)
