Columbus has become a controversial person in recent years mainly on how he treated the indigenous peoples and the havoc subsequent Europeans wrought on them and their culture for the last 600 plus years. I maintain that he was also bad at geography. That the Earth was round was not an issue among the educated of his day. The Earth’s size, however, was. The Earth’s circumference accepted by most scholars of that day was pretty close to the modern value of about 25 thousand miles. Columbus thought it was about 7 thousand miles less putting the Orient that much closer by sailing west from Europe. This was a minority opinion, but he convinced the king and queen of Spain to finance his venture based on it.
