description: Arnold of Villanova was born in the year 1240, and studied medicine with great success in the University of Paris. He afterwards travelled for twenty years in Italy and Germany, where he made acquaintance with Pietro d'Apone; a man of a character akin to his own, and addicted to the same pursuits. As a physician, he was thought, in his own lifetime, to be the most able the world had ever seen. Like all the learned men of that day, he dabbled in astrology and alchemy, and was thought to have made immense quantities of gold from lead and copper.
