I’ve managed to narrow it down, though. He was born sometime between late August and late October of 1451, which means he was a Leo, a Virgo, a Libra or a Scorpio. If I had to take a guess, I’d probably go with Leo.
See, Columbus was a fiery guy. Not only did he set off to discover a new world, but he showed determined arrogance and a refusal to accept “no” for an answer, even when it turned out many of his calculations were incorrect.
He also had quite a temper, he made dramatic decisions, he loved the ladies and he was able to charm his way to a new world.
History may not be able to determine Columbus’ sign, but Astrology can. I also like to think that Astrology is probably a better navigation tool for finding your way than Columbus ever had, right?
