3rd. century. During a stage performance before Emperor Diocletian in Rome, the actor Genesius portrayed a catechumen about to be baptized in a play satirizing the Christian sacrament. In the midst of the ceremony he was suddenly converted to Christianity. When presented to the Emperor, he declared his Christianity. Enbraged, Diocletian had him turned over to Plautian, prefect of the praetorium, who tortured him in an effort to force him to sacrifice to the pagan gods. When Genesius persisted in his faith, he was beheaded. Though the legend is an ancient one, it is no more than that. Genesius is the patron of actors. Feast day is Aug. 25.
