Francesco Petrarca (1304–1374), commonly known as Petrarch in the English-speaking world, is the great Italian master whose work helped to create the Renaissance sonnet craze in England. He was a Franciscan tertiary, a scholar of the Classics, a friend to Decameron author Giovanni Boccaccio, and an immensely popular poet in his day. Despite his religious vows, he had two children out of wedlock, and is best known for sonnets professing intense love for a woman named Laura.
