Columbus was quite a guy. His only curse he ever uttered when angry was “God take you.”
When he reached the New World on his last voyage, he became stranded there for a period of time and when the natives declined to give him an his men any food to tide them over, he used the onset of a solar eclipse which he was able to predict due to tables available to Europeans, and the totally awed natives gave them the food he requested.
Also, the native were inclined to be quite friendly to him, as they were frequent victims to the cannabilistic and violent Carib tribe, who were feared by all natives of the area.
Small correction—it was a lunar eclipse, not a solar eclipse, that Columbus used to his advantage. I think he was stranded on Jamaica and the governor in Santo Domingo knew he was there but wouldn’t rescue him because he didn’t like him.
