13. Arcangelo Corelli and Matteo Fornari
Corelli, one of the most influential composers of the 17th century, lived in Rome among a circle of gay artists who had favor with Cardinal Pietro Ottoboni and therefore enjoyed a certain level of discretion. While staying at the La Cancelleria, an all-male academy, he developed a long-term relationship with the violinist Matteo Fornari, according to research by Clive Paget. The relationship lasted two decades, and Fornari would oversee completion of some of Corelli’s unfinished works.
