_The Revenge of Bussy D'Ambois_ follows historical lines less closely than the "Byron" plays, but here, too, Grimeston's volume was Chapman's inspiring source, and the perusal of its closing pages gives a clue to the origin of this most singular of the dramatist's serious plays. The final episode included in the folio of 1607 was the plot by which the Count d'Auvergne, who had been one of Byron's fellow conspirators, and who had fallen under suspicion for a second time in 1604, was treacherously arrested by agents of the King while attending a review of troops. The position of this narrative (translated from P. Matthieu) at the close of the folio must have helped to draw Chapman's special attention to it, and having expended his genius so liberally on the career of the arch-conspirator of the period, he was apparently moved to handle also that of his interesting confederate. But D'Auvergne's fortunes scarcely furnished the stuff for a complete drama, on Chapman's customary broad scale, and he seems therefore to have conceived the ingenious idea of utilising them as the groundwork of a sequel to his most popular play, _Bussy D'Ambois_. He transformed the Count into an imaginary brother of his former hero. For though D'Ambois had two younger brothers, Hubert, seigneur de Moigneville, and Georges, baron de Bussy, it is highly improbable that Chapman had ever heard of them, and there was nothing in the career of either to suggest the figure of Clermont D'Ambois. The name given by Chapman to this unhistorical addition to the family was, I believe, due to a mere chance, if not a misunderstanding. In Grimeston's narrative of the plot against D'Auvergne he mentions that one of the King's agents, D'Eurre, "came to Clermont on Monday at night, and goes unto him [D'Auvergne] where he supped." Here the name Clermont denotes, of course, a place. But Chapman may have possibly misconceived it to refer to the Count, and, in any case, its occurrence in this context probably suggested its bestowal upon the hero of the second D'Ambois play. A later passage in Grimeston's history gives an interesting glimpse of D'Auvergne's character. We are told that after he had been arrested, and was being conducted to Paris, "all the way he seemed no more afflicted, then when he was at libertie. He tould youthfull and idle tales of his love, and the deceiving of ladies. Hee shott in a harquebuse at birds, wherein hee was so perfect and excellent, as hee did kill larkes as they were flying."
