Before Christopher Columbus and the Spanish Conquistadors landed on the island of "Borikén" (Puerto Rico), the Tainos who inhabited the island depended on their astronomical observations for the cultivation of their crops. In 1581, Juan Ponce de León II, the grandson of the Conquistador Juan Ponce de León, studied an eclipse and its effects on the island and was able to establish the exact geographical coordinates of San Juan with his observations.
