All authorities agree in attributing his death to poison, but neither Leoni nor Baldi hint at the person whose "envy" dictated that base vengeance.[*35] Giovio speaks positively as to detection having followed upon a searching inquiry, and points at those interested in the Camerino question as authors of the crime. Sardi and Tondini charge it upon Luigi Gonzaga, Count of Sabionetta, surnamed Rodomonte, the nephew of Francesco da Bozzolo, a condottiere who commanded Bourbon's cavalry at the assault of Rome, and who facilitated Clement's flight some months thereafter. This assertion, which is adopted by various writers, receives some confirmation from a story in the gossiping MS. we have already quoted, that Gonzaga, having accused Gian Giacomo Leonardi, a doctor of laws at Pesaro, of instigating the murder, was challenged by the latter, who thereby gained the favour of Duke Guidobaldo II., and with it the countship of Monte l'Abbate, near Pesaro.[36] On the other hand, this Rodomonte is stated in _Les Genealogies des Maisons Souveraines_ to have died in 1528. [Footnote *35: Cf. VIANI, _L'avvelenamento di Francesco Maria I. della Rovere_ (Mantova, 1902), and _La Morte di F.M. della Rovere_, in _Fanfulla della Domenica_, 23 March, 1902.] [Footnote 36: Relazione della Legazione di Urbino, Bib. Marucc. c. 308.] Whoever may have been author of the foul deed, it is agreed that the perpetrator was the Duke's Mantuan barber, who is generally said to have dropped a poisoned lotion into his ear. Baldi only mentions that he did it "in a new way," and gives no account of the medical examination of the body which, he asserts, took place. In an old chronicle of Sinigaglia, Guidobaldo is stated to have had the barber torn to pieces with pincers, and quartered in the streets of Pesaro.[37] [Footnote 37: Vat. Urb. MSS. No. 992.
