What is "anticato"

The Anticato (sometimes Anti-Cato; Latin: Anticatones) was a polemic written by Julius Caesar in hostile reply to Cicero's pamphlet praising Cato the Younger. The text is lost and survives only in fragments. Brutus, dissatisfied with Cicero's work, wrote a second pamphlet in praise of Cato and called, simply, "Cato," which provoked a reply from Octavian. Octavian's work is not known to have been called Anticato but must have been modeled on Caesar's reply to Cicero.
