[Sidenote: PERIODS OF WORK]

The literary work of Chaucer is conveniently, but not accurately,
arranged in three different periods. While attached to the court,
one of his duties was to entertain the king and his visitors in
their leisure. French poems of love and chivalry were then in
demand, and of these Chaucer had great store; but English had
recently replaced French even at court, and King Edward and Queen
Philippa, both patrons of art and letters, encouraged Chaucer to
write in his native language. So he made translations of favorite
poems into English, and wrote others in imitation of French models.
These early works, the least interesting of all, belong to what is
called the period of French influence.

Then Chaucer, who had learned the art of silence as well as of
speech, was sent abroad on a series of diplomatic missions. In
Italy he probably met the poet Petrarch (as we infer from the
Prologue to the Clerk's Tale) and became familiar with the works of
Dante and Boccaccio. His subsequent poetry shows a decided advance
in range and originality, partly because of his own growth, no
doubt, and partly because of his better models. This second period,
of about fifteen years, is called the time of Italian influence.

In the third or English period Chaucer returned to London and was a
busy man of affairs; for at the English court, unlike those of
France and Italy, a poet was expected to earn his pension by some
useful work, literature being regarded as a recreation. He was in
turn comptroller of customs and superintendent of public works;
