... principis aut deum placamentis decedebat infamia, quin iussum incendium...

decedebat infamia, etc.: "the rumor/notoriety did not cease/subside/die out [nor did it prevent] the belief that the fire had been deliberately started"; cf. the next note for the explanation of the subordinate subjunctive clause introduced by "quin" following here by an implied verb of hindering/preventing.
