About this time Antiochus made his second invasion of Egypt. And it happened that, for almost forty days, there appeared over all the city golden-clad cavalry charging through the air, in companies fully armed with lances and drawn swords—troops of cavalry drawn up, attacks and counterattacks made on this side and on that, brandishing of shields, massing of spears, hurling of missiles, the flash of golden trappings, and armor of all kinds. Therefore everyone prayed that the apparition might prove to have been a good omen. –2 Maccabees 5:1-5 (NRSV)
