In his early years, Saint Jerome was educated by the famous Roman grammarian, Aelius Donatus. At age 12, he traveled to Rome to study grammar, philosophy, and rhetoric. While very smart, during that time, Jerome behaved immorally and pursued pleasures with women even though he knew it to be wrong. He would eventually change his ways and traveled to various locations building his skills in rhetoric and in translations. While his quick wit and sarcasm sometimes got him in trouble with some, few doubted his knowledge and skill. He is best known for his translation of the Bible from Hebrew and Old Latin to the current languages of the day.
