AGONISTICUS, in Church History, a name given by Donatus to such of his disciples as he sent to fairs, markets, and other public places, to propagate his doctrine; for which reason they were also called Circuitores, Circelliones, Catropita, and at Rome Montenses. They were called Agonistici, from the Greek agon, combat, being sent as it were to fight and subdue the people to their opinions.
