Another event which seemed likely to be favourable to Geneva was approaching. The pope, as we have said, had forced a coadjutor upon the bishop, and the latter had chosen Pierre de la Baume, an ecclesiastic of high family, a scion of the illustrious house of the counts of Montrevel, whom he looked upon as a son. Pierre, who was abbot of Suze and St. Claude, and bishop of Tarsus _in partibus_, came to Geneva about the time of Bonivard’s liberation in 1521 to take possession of his charge. On the 25th of January a _Te Deum_ was sung for that purpose at St. Pierre’s by the Bishop of Maurienne. Everybody knew that the coadjutor would soon be bishop and prince; accordingly all passions were aroused, and after mass, the mamelukes endeavoured to gain over the future bishop to their side. Besançon Hugues, who desired to see Geneva catholic and episcopal, but free, waited upon the prelate; reminded him, to pave the way for a good reception, that one Hugues, his great-uncle, had been cardinal, and perceiving that he had to deal with a frivolous, vain, pleasure-seeking man, and who, as a younger son, was ambitious to rise at least as high as his elder brothers, he strove to make him understand that, far from submitting to the duke, he should remember that the Bishop of Geneva was _prince_, while the duke was only vassal. Pierre de la Baume, a weak man, ever halting between two opinions, carried away by the honesty and eloquence of the Genevan citizen, gave him his confidence. Besançon Hugues remained ever after his most confidential adviser.[302]
