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, Catropites, Coropites, and at Rome Montenses. They were called Agonistici, from the Greek αγών, combat; in regard they were sent, as it were, to fight, and subdue the people to their opinions.
