Boustrophedon

Nope, it's not a dinosaur; it's a cool word. It's the way the Ancient Greeks used to read: forwards and right to left on this line, then backwards and left to right on the next. Boustrophedon means "as the ox plows" - that is when you turn at the end of the row and go the other way. This and other interesting stuff is in the new book I bought on Saturday: Ox House Stick: the history of our alphabet.
