The love of the Moon


Christopher Columbus’ ship was shipwrecked for a short time in the island of Jamaica. His men threatened mutiny, and to compromise the situation, the indigenous, tired of exchanging little mirrors and accounts, refused to supply them with food.
The situation was hopeless and Columbus, to calm down his men, promised them food and a meeting with the chief of the indigenous people that same night.

-You know that you have all angered me with your poor cooperation, I will make the moon turn red with blood and then it will dissapear!
The indigenous chiefs looked at the moon to make sure the threats of Columbus were real, terrified, they asked him to resurrect the moon, promising to continue bringing food to him and his crew.
Columbus moved his arms, as if he were calling someone, and assured them:
-The moon will appear new this same night, but if you take back your word again, it will return to how it was.
After that, he returned to his quarters satisfied, congratulating the men for bringing the Ephemerides of the famous mathematician Regiomontanus, who predicted the eclipse that just happened.
Regiomantanus also wrote about angles, and measuring in degrees, minutes, and seconds.
