βιαων, in rhetoric, denotes a kind of counter-argument, whereby something alleged for the adversary is retorted against him, and made to conclude a different way; for instance, Occidit, quia adfitit interficio. —Sic, Immo quia adfitit interficio, non occidit; nam si id efset, in fugam me concessefem. "You killed the person, because you were found standing by his body. Biaum, Rather I did not kill him because I was found standing by his body; since, in the other case, I should have fled away."

Biaum, in the Grecian laws, was an action brought against those who ravished women, or used violence to any man's person.
