St. Jerome, who was born Eusebius Hieronymous Sophronius, was the most learned of the Fathers of the Western Church. He was born about the year 342. The Church owes much to St. Jerome. While his great work was the Vulgate, his achievements in other fields are valuable; to him we owe the distinction between canonical and apocryphal writings; he was a pioneer in the field of Biblical archeology, his commentaries are important; his letters, published in three volumes, are one of our best sources of knowledge of the times.

St. Jerome has been a popular subject with artists, who have pictured him in the desert, as a scholar in his study, and sometimes in the robes of a cardinal, because of his services for Pope Damasus; often too he is shown with a lion, from whose paw, according to legend, he once drew a thorn. Actually this story was transferred to him from the tradition of St. Gerasimus, but a lion is not an inappropriate symbol for so fearless a champion of the faith.
