It was impossible that a mind, from infancy friendly to art and books, should not be struck by this general expansion; the charm of this literary springtime was too penetrating for Chaucer not to feel it; he followed a movement so conformable to his tastes, and we have a proof of it. Before his journeys he was ignorant of Italian literature; now he knows Italian, and has read the great classic authors of the Tuscan land: Boccaccio, Petrarch, and Dante. The remembrance of their works haunts him; the "Roman de la Rose" ceases to be his main literary ideal. He was acquainted with the old classics before his missions; but the tone in which he speaks of them now has changed; to-day it is a tone of veneration; one should kiss their "steppes." He expresses himself about them as Petrarch did; it seems, so great is the resemblance, as if we found in his verses an echo of the conversations they very likely had together by Padua in 1373.[480] In the intervals between his missions Chaucer would return to London, where administrative functions had been entrusted to him. For twelve years, dating from 1374, he was comptroller of the customs, and during the ten first years he was obliged, according to his oath, to write the accounts and to draw up the rolls of the receipts with his own hand: "Ye shall swere that ... ye shall write the rolles by your owne hande demesned."[481] To have an idea of the work this implies, one should see, at the Record Office, the immense sheets of parchment fastened together, one after the other, which constitute these rolls.[482] After having himself been present at the weighing and verifying of the merchandise, Chaucer entered the name of the owner, the quality and quantity of the produce taxed, and the amount to be collected: endless "rekeninges!" Defrauders were fined; one, John Kent, of London, having tried to smuggle some wools to Dordrecht, the poet, poet though he was, discovered the offence; the wools were confiscated and sold, and Chaucer received seventy-one pounds four shillings and sixpence on the amount of the fine John Kent had to pay.
