Of course, there is no concrete evidence of Handel's having engaged in homosexual activity. But as Harris makes clear, there is enough circumstantial evidence to justify those.
Music historian Ellen Harris leads on the case for Handel’s homosexuality, arguing that his cantatas exhibit a clear homosexual subtext in her book Handel as Orpheus.
Handel was one of the best-known composers of the Baroque era, especially famous for his smash-hit oratorios like The Messiah. Some modern-day musicologists consider him to be LGBTQ+.
My curiosity grew out of a comment made by a classical music critic on the radio that "Händel never married and led a very private personal life. His closest friends, however, were known to be gay." Note: I'm not sure whether this question is on topic here. Feel free to closevote it if it isn't.
