EXPLOITS OF MEMNON AT SEA — HIS DEATH. 105 gods ratified by a stoi'm of tliunder and. lightning during the ensuing night, i At Gordium, Alexander was visited by envoys from Athens, entreating the liberation of the Athenian prisoners taken at the Granikus, who were now at Avork chained in the Macedonian mines.
