After all, they liked the guy. Besides, he was great to have around during social gatherings talking about his inventions and latest conversations with bishops and the Pope. For the superstitious party-pooper, sometime during the evening, Leo would present the antiquated thinker with a quick penciled pocket size portrait of said person, thus creating yet another ally.
Some commissioned, shows that he had a deep sense of self and God. He understood Universal Law and the perfection of nature, and since there was nothing to watch on television during the fifteenth and sixteenth centuries, he had plenty of time to transform his visions into physical forms.
