Here's what we do know:
* Casanova kept a detailed diary: This diary documented his many conquests, but it's not a complete record and likely contains some exaggeration.
* Estimates vary wildly: Some scholars estimate he had hundreds of lovers, while others believe it was closer to a few dozen.
* His true number is a mystery: The exact number remains a subject of debate and speculation.
While it's fun to imagine Casanova's many conquests, it's important to remember that his romantic life was just one part of his complex and fascinating personality.
