In my lifetime the reputation of Christopher Columbus has gone from the visionary explorer and Admiral of the Ocean Sea as he titled himself to that of a slave trading , genocidal manic in some of the most extreme diatribes that I've read. I think the truth lies somewhere in between. He was a man of his time, where slavery was an excepted practice. He was clearly a master navigator, if a bit obsessive, and if he'd stuck to exploration, I dare say his reputation would would have remained intact. Alas, he was an incompetent colonial administrator, and both unable to control his settlements, nor able to fulfill his over-reaching promises to his sovereigns. He is also as far as I can tell, and neglected as the originator of the mystery meat phrase, "it tastes like chicken."
"While going around on of the lagoons I saw a serpent which we killed with lances, and I am bringing Your Highness the skin. When it saw us, it went into the lagoon, and we followed it in because the water is not very deep. This serpent is about 6 feet long. I think there are many such serpents in these lagoons. The people here eat them and the meat is white and tastes like chicken."
