Lucretia Borgia is quite famous still, considering she died in 1519. However as common as her name is associated with poisoning and other imprecations, few have read her history - no matter how literate.
To that end, I recommend elucidation via the excellent biography 'Lucretia Borgia', a translation from the German. Now over 100 years old, and concerning events nearly 5 centuries past, the book is accessible and interesting. Available in several formats from Project Gutenburg. Enjoy!
