Sebastian Castello (name variations: Castalio, Chatelion; 
1515 - 
December 29, 
1563) was the 
rector of the College of 
Geneva (obviously not Geneva College, maybe what is today Université de Genève?). He was born in St. Martine du Fresne 
(in Switzerland?). His ideas conflicted with those of 
John Calvin who had Castello dismissed from his position in 
1544. He moved to 
Basel, 
Switzerland where he became a professor of 
Greek. He wrote about tolerance, that the government has no right to insist on the specific form of faith and to expell other people not sharing it. This was outstanding at that time and in many parts of the world it still is.
