Frederick II was a versatile monarch. He was able to master 7 languages in the middle ages when he was under-educated. He also founded a university and published poetry collections.
But he also has a cruel and terrifying side. He likes to experiment, he once gave some newborn babies to deaf-mute people to raise, just to observe how language originated.
I really admire his imagination, his use of the power of his monarch is truly extraordinary. He once soaked the prisoner in a wine barrel and drowned slowly to see if there was any soul in the world.
