QUES: The efforts of military commanders to channel the divine will were on occasion less successful. In the early days of Rome's war against Carthage, the commander Publius Claudius Pulcher (consul 249 BC) launched a sea campaign "though the sacred chickens would not eat when he took the auspices." In defiance of the omen, he threw them into the sea, "saying that they might drink, since they would not eat. He was defeated, and on being bidden by the senate to appoint a dictator, he appointed his messenger Glycias, as if again making a jest of his country's peril." His impiety not only lost the battle but ruined his career.

What general was consul in 249 BC?
What is the answer?
ANS: Publius Claudius Pulcher
