The classical languages of the Ancient Mediterranean world influenced every European language, imparting to each a learned vocabulary of international application. Thus, Latin grew from a highly developed cultural product of the Golden and Silver eras of Latin literature to become the "international lingua franca" in matters diplomatic, scientific, philosophic and religious, until the 17th century. Long before this, Latin had evolved into the Romance languages and Ancient Greek into Modern Greek and its dialects. In the specialised science and technology vocabularies, the influence of Latin and Greek is notable. Ecclesiastical Latin, the Roman Catholic Church's official language, remains a living legacy of the classical world in the contemporary world.
