Leon Africanus or Hassan al-Wazzan was born in Muslim Grenade, raised up in Fez, in diplomatic mission in the Middle East, detained in Italy as a slave, freed by Pope Leon X, that induced to write and publish "Description of Africa". Even if his book was mentioning the practices from other religions, it was so intelligently written Inquisitors could not find the argumentative way to condemn it formally. So, little by little, Leon's book turned out to be the book for the ones that didn't want to be condemned formally, let's say for the people that felt guilty and for some sin they were feeling guilty. That's how in Mallorca, they burned up Jews and catholic-converted Jews, whose only fault was to possess Leon Africanus's book, up to 19th cent.
