Interesting Fact The Archbishop of Scotland who thought he was suffering from consumption, sent for Cardano to come and cure him. With Cardanos help, he made a complete recovery from consumption, which he was not suffering from.

Famed Work Ars Magna Liber de ludo aleae De vita propria liber (The Book of My Life) Practica Arithmetic (Practical Arithmetic)

Interesting Fact Cardano was eventually forbidden to lecture or publish books. He was imprisoned in 1570 because he cast the horoscope of Christ.

Influenced by Agricola He felt that the sense of hearing and the use of spoken words were not indispensable to understanding ideas.

Cardano was the first to make a connection between deafness and mutism. He found this subject interesting because his oldest son was deaf in one ear and Cardano, himself, had a problem with stuttering.

Quote The writing is connected to speech and the thought, but written letters and ideas could be brought together without the participation of read sounds.

Although Cardano wrote about the deaf being able to learn even thought they had no verbal communication, he never went further to study it.
