Columbus’ Calculation Mistake
Columbus learned of Alfraganus's (Muslim astronomer) estimate that one degree of latitude spanned 56⅔ miles, but did not realize that this was expressed in the Arabic mile (about 1,830 m) rather than the shorter Roman mile he was familiar with (1,480 m). He therefore estimated the circumference of the Earth to be about 19,000 miles, whereas the correct value is 25,000 miles. Based on these calculation Columbus could reach the East Indies (India, China, Spice Islands) faster by traveling West.

Another Columbus Mistake
Columbus thought he landed in India. He thought this in part because of the darker skin of the native people there.
