Tanzanite's Castle Full of Books

Since my upcoming read has some of the Borgia family as at least secondary characters and with the 2011 Showtime series about the family I thought it was time to start learning a little bit more about them.  Rodrigo Borgia was born in 1431 and after studying law, worked his way up the church hierarchy.  In 1492 he was elected pope (amid allegations of bribery) and he took the name of Alexander VI.  Despite his long career in the church, Rodrigo had several children.  Four - including Cesare and Lucrezia (among the more well known of the Borgia family) -were by the same woman, Vannozza dei Cattani.  He died in 1503.
