Jerusalem Delivered
Renaud de Montauban should not be confused with Rinaldo, the son of Bertoldo and reputed founder of the House of Este in Torquato Tasso's epic poem "Jerusalem Delivered" (1580), though this second character is made out to be a descendant of the original paladin's sister Bradamante. The second Rinaldo is the son of Bertoldo and Sophia and he lived during the time of the First Crusade. According to legend, Bertoldo is the son of Azzo II, a real person who was Count of Este (Orlando Furioso III: 29-30). One of Azzo II's sons was Welf IV, (Welf I, Duke of Bavaria). "Jerusalem Delivered" states that Bertoldo is related to Welf IV. (Jerusalem Delivered XVII: 81).
