Sperone Speroni degli Alvarotti (1500–1588) was an Italian Renaissance humanist, scholar and dramatist. He was one of the central members of Padua's literary academy Accademia degli Infiammati and wrote on both moral and literary matters. Sperone was the son of Bernardino Speroni degli Alvarotti and Lucia Contarini. In 1518 he obtained the artibus degree from the University of Padua and joined the Guild (Sacro Collegio) of artists and physicians. He lectured on philosophy at Padua, under the Chair of Logic. He interrupted his teachings to study at Bologna under Pietro Pomponazzi but, after Pietro's death, returned to Padua where he obtained an Extraordinary Chair of Philosophy, a post he held for another three years. His literary career began with the publication of the Dialoghi ("Dialogues") at Venice (1542). Very famous and influential was his polemic with Giovan Battista Giraldi about the principles of theatre, involving Giraldi's tragedy Orbecche as well as Speroni's tragedy Canace. Between 1560 and 1564 he lived in Rome, where he became a close friend of Annibal Caro and frequented the meetings of the Accademia delle Notti Vaticane. He then returned to Padua, where he continued his literary production. He died in Padua in 1588.
