Mr. Green, Mr. Green, Columbus was just a lucky idiot. Yeah, no. Here's a little rule of thumb, me from the past. If you're not an expert in something, don't pretend to be an expert. This is going to serve you well both in your academic career and in your kissing career. Moving on! So unlike me from the past, I'd argue that Columbus has a deserved reputation in history, but was he really the greatest sailor of the 15th century?
