The Iliad 750? BC-650? BC Homer 1834

It was built partly on three hills, the buttresses of a long ridge which turned a wide river, and on the ridge itself, and partly on the flat shore of the river, on either side, hillward and plainward: but a great white wall girt it all about, which went right over the river as a bridge, and on the plain side it was exceeding high, so that its battlements might be somewhat evened with those of the hill-wall above.
