The English literature is one of the richest sources of world literature. It has contributed much to the entire body of literature in the world. It has so much to discuss. However, we, first of all, should know who the creator of the English language as a literary language was, who brought it to the stage of it, and who put it in higher status than French. As would-be English philologists we should be certainly aware that it was Geoffrey Chaucer who lived in the 14th century and wrote his masterpiece “The Canterbury Tales” in the English language.  Chaucer’s contribution to English literature is usually explained by the following:  The Canterbury tales sum up all types of stories that existed in the middle ages. He managed to show different types of people that lived during his time and through these people he showed a true picture of the life of the 14th century. The pilgrims range in rank from a knight to poor plowman. Only the very highest and lowest rank – the nobility and the serfs – are missing. In Chaucer’s age the English language was still divided by dialects, though London was rapidly making east midland into a standard language. Chaucer was the creator of a new literary language. He chose to write in English, the popular language of common people, though aristocracy of his time read and spoke French. Chaucer was the true founder of English literature.
