At the time Chaucer's writings were not just literary adventures, but also a means of convincing the world that poetry and science, tragedy and astrology, could all be explored through the English language. French was still England's aristocratic language of choice when Chaucer was born; Latin was used for university education, theological discussion, and for burying the dead. Could a hybrid tongue such as English ever generate great writing to compare with French and Italian? Chaucer, miraculously, believed that it could, through gradual expansion of expressiveness and scientific precision. He was never paid to do this; he was valued, rather, as a capable civil servant, regulating the export of wool and the building of seating for royal tournaments.

Such experiences, however, fed his writing, achieving a range of social registers, from noble tragedy to barnyard farce, unrivalled for centuries. His tale-telling geography is vast, his fascination with varieties of religious belief endless, and his desire to voice female experience especially remarkable. In this book David Wallace introduces the life, performance, and poetry of Chaucer, and analyses his astonishing and enduring appeal.
