Madonna Giovanna de’ Catanei (wife of Don Giorgio della Croce, and, after his death, of Don Carlo Canale,) was certainly his mother. Two official inscriptions bear witness to this. The first, which was published by Signor Gnoli in the _Nuova Antologia_ of the first of February 1881, refers to a house on Campo di Fiori which she left as an endowment for anniversary masses for the repose of the souls of herself and her two husbands named. The deed is the work of Messer Andrea Caroso, Notary Public, and is dated the fifteenth of January 1517. In it she is called “Vanoza Catanea _madre del Duca Borge_.” The second is her epitaph on her tomb in Santa Maria del Popolo (Forcella. Iscrizioni delle chiese di Roma I. 335) shewing her natural pride at finding herself the mother of two dukes, a prince duke, and a sovereign duchess. “Faustiae Cathanae, _Caesare Valentiae_, Joannae Candiae, Jufredo Scylatii, et Lucretia Ferrariae ducib. filiis nobili Probitate insigni religioni eximia pari et aetate et Prudentiae optime de xenodochio Lateranen. Meritae Hieronimus Picus fidei commis. procur. ex test(amento) pos(uit). Vix(it) ann. LXXVI m. IV d. XIII. Objit anno M.D.XVIII. XXVI Nov.” In the absence of anything more authoritative than the foregoing, the story of Varillas remains the most probable solution of the mystery. The Lord Alexander P.P. VI never named, never treated, Duke Cesare as His son; never shewed for him the paternal love and affection which He shewed for his bastards, Don Pedro Luis, Madonna Girolama, Duke Juan Francisco, Duchess Lucrezia, Prince Gioffredo, Madonna Laura, Duke Giovanni. Yet Duke Cesare was splendid and superb; his abilities were immense, and pre-eminently useful to the Pope. And the Pope used him on all occasions as His most serviceable subject, rewarding him with lavish generosity for the service which he rendered. Between the Duke and his Sovereign Patron, there was a certain privileged and familiar confidence: but never intimate relationship, or filial or paternal love. The status of Cardinal Giuliano della Rovere; his furious, blind, instinctive, and eternal hatred of the Lord Alexander P.P. VI and of every one connected with Him, is susceptible of an extremely human explanation. It bears the strongest possible resemblance to that very singular and very distinguishable passion of revengeful jealous rage which consumes the vulgar man in regard to a superior (in rank, breeding, or physique,) who shall have supplanted him in the favours of a lady.
