His translations of the books of the great learned rabbi Abraham Aben Ezra

In the 15th century, Christopher Columbus used al-Farghani’s estimate for the Earth’s circumference as the basis for his voyages to America. However, Columbus mistook al-Farghani’s 7091-foot Arabic mile to be a 4856-foot Roman mile.

This error caused him to underestimate the Earth’s circumference, leading him to sail to North America while he believed that he was taking a shortcut to Asia.[20][21]
