Columbus Uses Eclipse: Science as Weapon Against Natives

Christopher Columbus was stranded on Jamaica's north coast in February 1504, his ships worm-eaten and unseaworthy, his crew starving and on the verge of mutiny. The Taino people had been feeding the Spaniards for months but were growing resentful. Columbus knew from his copy of Regiomontanus's astronomical almanac that a total lunar eclipse was coming on February 29. He summoned the local chiefs and told them that his God was angry at their refusal to continue providing food and would darken the moon as punishment. When the eclipse began on schedule, the Taino were terrified and begged Columbus to restore the light. He retreated to his cabin, timed the eclipse's duration from the almanac, and emerged just before totality ended to announce that God had forgiven them. The food supplies resumed immediately. The episode demonstrated how European scientific knowledge functioned as a tool of colonial power over populations without access to the same astronomical traditions.
