This is from my reading in History of the Reformation in Europe in the Time of Calvin by J. H. Merle D'Aubigne
Aonio Paleario was an Italian Reformer in the 16th century. He was born in 1503. In 1520 he went to Rome to study Homer, Virgil and the like, and in 1536 he published a poem in Latin. He began reading the scriptures and discovered the doctrine of justification by faith. He married, and had two sons and two daughters. Some monks formed a plot against him to convict him of heresy, but he defended himself and was declared innocent. Thirty years later he was arrested again for heresy. He was accused of denying purgatory and for saying that Christians are justified by faith alone (Sola Fide). He was hanged and then burnt in Rome on July 3rd, 1570. Many people forget that there was a small Reformation in Italy because it died out and we do not see fruits of it today.
