Although the need to learn foreign languages is almost as old as human history itself, the origins of modern language education are in the study and teaching of Latin in the 17th century. In the Ancient Near East, Akkadian was the language of diplomacy, as in the Amarna letters.^[4] For many centuries, Latin had been the dominant language of education, commerce, religion, and government in much of the Western world. By the end of the 16th century, it had largely been displaced by French, Italian, and English. John Amos Comenius was one of many people who tried to reverse this trend. He composed a complete course for learning Latin, covering the entire school curriculum, culminating in his Opera Didactica Omnia, 1657.

In this work, Comenius also outlined his theory of language acquisition. He is one of the first theorists to write ^[5] systematically about how languages are learned and about pedagogical methodology for language acquisition. He held that language acquisition must be allied with sensation and experience. Teaching must be oral. The schoolroom should have models of things, and failing that, pictures of them. As a result, he also published the world's first illustrated children's book, Orbis sensualium pictus. The study of Latin diminished from the study of a living language to be used in the real world to a subject in the school curriculum. Such decline brought about a new justification for its study. It was then claimed that its study of Latin developed intellectual ability, and the study of Latin grammar became an end in and of itself.
