Background about four members of this prominent Italian Renaissance family that includes these "members [who] in particular are remembered, if only vaguely, as remarkable examples of greed and evil. Two were popes: Calixtus III (Alonso Borgia) and Alexander VI (Rodrigo Borgia). ... Cesare Borgia, was, for a time, a cardinal. ... The fourth member has become a metaphor for feminine evil: Lucrezia Borgia, sister of Cesare." Also includes a bibliography. From truTV.
