During a battle with Scythians in Macedonia on April 29, 1091, Byzantine emperor Alex­ius I Comnenus noted the midday sun “shedding its rays,” reported his daughter Anna Comnena in the Alexiad. He dispatched local peasants to bring water in skins or jars to his troops, who “sipped a drop of water, then returned to the fray.” The newly hydrated Byzantines wiped out their enemies, and a chant began: “All because of one day the Scythians never saw May.”
