High Quality Content by WIKIPEDIA articles! Marcus Calpurnius Bibulus (d. 48 BC) was a politician of the late Roman Republic. Bibulus was the son in law of Marcus Porcius Cato Uticencis. In 59 BC he was elected consul, supported by the optimates, conservative republicans in the Senate and opponents of Julius Caesar's triumvirate. In this, Caesar, also elected consul in 59, had failed in securing the election to the consulship of his ally Lucius Lucceius. Nevertheless, with the combined strength of the triumvirate, Caesar was largely able to circumvent the authority of Bibulus and the optimates. Bibulus' only major act as consul was to veto Caesar's bill giving land in Campania to Pompey's soldiers, and to then declare that the rest of the days on which the Centuriate Assembly could meet would be religious holidays. Caesar presented his bill at the Assembly anyway, and when Bibulus tried to intervene, the crowd broke his fasces and dumped feces on him. He retired from the Forum, leaving Caesar with complete control over the consulship, although he occasionally issued complaints against Caesar, which led to attacks on his house from Caesar's supporters, the populares.
