Geoffrey Chauser’s most famous work, The Canterbury Tales, is a collection of stories of 31 pilgrims travelling to Canterbury. In one of the London taverns of that time, the Tabard Inn, the narrator meets a motley company of pilgrims gathered on their way to the relics of St. Thomas Becket, Archbishop of Canterbury, kept in Canterbury Cathedral. The group’s pilgrimage is reasoned by religious purposes – they are going to Canterbury to pay homage to Thomas Becket.
The Canterbury Tales is considered a social document of Chaucer's age because of its realistic depiction of the society. It presents almost all characters found in a society except for aristocratic class and beggars.
