Saint Catherine of Alexandria is invoked as patron of preachers. Catherine of Alexandria was traditionally venerated as a noblewoman of fourth-century Alexandria, martyred in the persecution of the Emperor Maximinus II (or possibly Maxentius) around 305-313. Her legendary Acts, which circulated widely in the East from at least the seventh century, present her as a learned Christian virgin who, when summoned by the emperor to defend her faith in public disputation, confounded fifty pagan philosophers, who were converted and executed; condemned to be broken on a spiked wheel, she was delivered when the wheel itself shattered; and was finally beheaded.The historical core of her cult is uncertain - she is not mentioned in the most ancient martyrologies - but her veneration was firmly established by the ninth century and exploded in the Latin West after the discovery of relics venerated as hers at the great monastery of Mount Sinai (now Saint Catherine's Monastery), an attribution that gave the monastery and the surrounding mountain her name.
