"Whether this is true or not I can not say..."
This book has great scope covering the geography, history, anthropology and zoology of the known world a the time. It covers Persia, Scythia, Egypt and Syria. There might be a thing or two about Greece also. Some of it might even be true. But the story is so compelling as not to matter, and Herodotus says as much many times.
He sounds very much like my Oxfordian grandfather, if I had one.
