After hearing that the 16th-century astronomer Copernicus was to be reburied with honors in a Polish ceremony, I checked the Wikipedia entry. Woah!

Among the great polymaths of the Renaissance, Copernicus was a mathematician, astronomer, physician, quadrilingual polyglot, classical scholar, translator, artist,[3] Catholic cleric, jurist, governor, military leader, diplomat and economist. Among his many responsibilities, astronomy figured as little more than an avocation – yet it was in that field that he made his mark upon the world.
