I'm reading up on Maurizio Cazzati (1616-1678), using the non-academic sources available to me.
Most refer to his time as maestro di cappella at San Petronio in Bologna as controversial; some suggest he was forced out in 1671. A couple of sources describe the end thus:
"…a controversy with the organist Giulia Cesare Arresti over musical errors in the Kyrie of his Missa primi toni Op.17…"
I cannot imagine living in a time when writing a piece with a badly-prepared dissonance would result in being sacked.
