Note 10 — BOOK V.

This celebrated light-house, situated at the entrance of the port of Alexandria, was built by Sostratus of Cnidos on an island which bore the same name, at the expense of eight hundred talents. It was square, constructed of white stone, and with admirable art, exceedingly lofty, and in all respects of great dimensions. It contained many stories, which diminished in width from below upwards. The upper stories had windows looking seaward, and torches or fires were kept burning in them by night, in order to guide vessels into the harbour.—Dict. of Greek and Roman Antiq.
