BUSIRIS, in Ancient Geography, a city of the Lower Egypt, to the south of Leontopolis, on that branch of the Nile called Busiriticus: Built by Busiris, noted for his cruelty, and slain by Hercules, (Ovid, Virgil, Diodorus Siculus). Strabo denies such a tyrant ever existed; Isocrates has written his panegyric. In this city there stood a grand temple of Isis, which gave it the appellation of the city of Isis. It was destroyed on a revolt by Diocletian.
