Columbus uses a lunar eclipse in Jamaica

1504Notable

Stranded in Jamaica, Columbus uses an almanac to predict the lunar eclipse of February 29, 1504, and persuades local people to resume supplying his crew with food.

The story

In 1503 Christopher Columbus's fourth voyage ended with his worm-eaten ships beached on the north coast of Jamaica. He and his crew survived on food supplied by the local Taino, but relations soured and the supply dried up. Columbus, who carried the printed astronomical tables of the German astronomer Regiomontanus, saw that a lunar eclipse was due on February 29, 1504. He warned the Taino leaders that God would show His displeasure, and when the Moon went red and dark the people agreed to supply food again.

The account comes from Columbus's son Ferdinand and other contemporaries, and historians generally accept it. The episode shows how a printed table, made in Europe in the 1470s, could be turned into political leverage far away. It also stands behind a long line of stories about eclipses used by outsiders, such as Mark Twain's A Connecticut Yankee in King Arthur's Court. Columbus and his crew were rescued in 1504 and returned to Spain.

Why it mattered

  • Is an early example of printed scientific tables being used in the field, far from the place they were made.
  • Became a model for later stories of eclipse prediction as leverage, as in Twain's 1889 novel.
  • Illustrates how European astronomy served exploration and the navigation of the Atlantic.
