[Casanova’s] most confusing moment came when he met a particularly lovely teenage castrato named Bellino in an inn. Casanova was bewitched, going so far as to offer a gold doubloon to see the boy’s genitals. In an improbable twist, when Casanova grabbed Bellino in a fit of passion, he discovered a false penis: it turned out that the castrato was a girl, who historians have identified as Teresa Lanti. She had taken up the disguise to circumvent the ban on female singers in Italy. The pair became lovers, but Casanova dumped her in Venice; after bearing a son that may or may not have been his, Lanti “came out” as a female and went on to become a successful singer in more progressive opera houses of Europe, where women were allowed on stage.
