Today’s saint is one who was quite popular during the Medieval era. Our saint is Saint Catherine of Alexandria:
Saint Catherine of Alexandria, also known as Saint Catherine of the Wheel and The Great Martyr Saint Catherine (Greek: ἡ Ἁγία Αἰκατερίνα ἡ Μεγαλομάρτυς) is, according to tradition, a Christian saint and virgin, who was martyred in the early 4th century at the hands of the pagan emperor Maxentius. According to her hagiography, she was both a princess and a noted scholar, who became a Christian around the age of fourteen, and converted hundreds of people to Christianity. Over 1,100 years following her martyrdom, St. Joan of Arc identified Catherine as one of the Saints who appeared to her and counselled her.
The Orthodox Church venerates her as a Great Martyr, and celebrates her feast day on 24 or 25 November (depending on the local tradition). In the Catholic Church she is traditionally revered as one of the Fourteen Holy Helpers. In 1969 the Catholic Church removed her feast day from the General Roman Calendar; however, she continued to be commemorated in the Roman Martyrology on November 25. In 2002, her feast was restored to the General Roman Calendar as an optional memorial.
In recent times there is some controversy over whether she was a historical person or a compilation of historical figures meshed together in one saint. Those interested in learning more about this figure can check out her wiki, located here.
