Okay, ugh, I have read enough in
this book about
William Davenant's
syphilis treatments. "He had spent an unspecified period of time with his head sewn into a medicated hood..." That's one of the milder ones.
Lee Durkee told me that Davenant used to hint to everyone that
Shakespeare was his real dad. The book mentions as much, and says that he usually let that slip while drunk.
