International Translation Day Hero

Saint Jerome

Saint Jerome (c. 347–420 AD) is widely regarded as the patron saint of translators. He is best known for translating most of the Bible into Latin, a version known as the Vulgate, which became the official Latin Bible of the Catholic Church. His work was monumental, requiring deep linguistic and scholarly effort to bridge ancient texts with the contemporary language of his time. His feast day, September 30, was chosen for International Translation Day.

History of International Translation Day

Can you imagine a world without translators? Imagine you could never read your favorite books, understand foreign cinematic masterpieces, or enjoy that eccentric European T.V. series. A world without translators would mean a world where the great literary works of Homer’s “Iliad” would not be known, Euclid’s mathematical achievements would have remained hidden and most importantly, the world of diplomacy would not exist.

Translators are an indispensable part of society and play an important role in bringing nations together, facilitating dialogue, understanding, and cooperation, helping interpersonal communication, preserving clarity, and ensuring a positive climate and productiveness in international public discourse.

In 1953, the International Federation of Translators started International Translation Day. The day is celebrated annually on September 30, which is the day of the feast of St. Jerome, the Bible translator, who is seen as the patron saint of translators. St. Jerome was a priest from Northeast Italy who is known for translating the Bible into Latin from Greek manuscripts of the New Testament.

This day pays tribute to the work of translators who help wipe out our differences by breaking down the language barriers. International Translation Day helps promote cultural heritage and mutual respect in our changing world.
As globalization increases, the work of translators has become integral to sustain the structures and processes of trade markets. Translators sit at the junction point that impacts the development of business, science, medicine, technology, politics, and a host of other areas.

This day provides us with an opportunity to appreciate the work of translators, interpreters, and others in the language service industry.
