30 September celebrates the feast of St. Jerome, the Bible translator who is considered the patron saint of translators. The theme for International Translation Day 2018 is “Translation: promoting cultural heritage in changing times”.
St. Jerome was a priest from North-eastern Italy, who is known mostly for his endeavour of translating most of the Bible into Latin from the Greek manuscripts of the New Testament. He also translated parts of the Hebrew Gospel into Greek.
