§ 11. 1370-1372. In the course of the next ten years (1370-80), the poet was attached to the court, and employed in no less than seven diplomatic services. The first of these occasions was during the summer of 1370, when he obtained the usual letters of protection, dated June 10, to remain in force till the ensuing Michaelmas[60]. That he returned immediately afterwards, appears from the fact that he received his half-yearly pension in person on Tuesday, the 8th of October[61]; though on the preceding occasion (Thursday, April 25), it was paid to Walter Walssh instead of to himself[62]. In 1371 and 1372, he received his pension himself[63]. In 1372 and 1373 he received 2l. for his clothes each year. This was probably a customary annual allowance to squires[64]. A like payment is again recorded in 1377. Towards the end of the latter year, on Nov. 12, 1372, Chaucer, being then 'scutifer,' or one of the king's esquires, was joined in a commission with James Provan and John de Mari, the latter of whom is described as a citizen of Genoa, to treat with the duke, citizens, and merchants of Genoa, for the purpose of choosing an English port where the Genoese might form a commercial establishment[65]. On Dec. 1, he received an advance of 66l. 13s. 4d. towards his expenses[66]; and probably left England before the close of the year. § 12. 1373. CHAUCER'S FIRST VISIT TO ITALY. All that is known of this mission is that he visited Florence as well as Genoa, and that he returned before Nov. 22, 1373, on which day he received his pension in person[67]. It further appears that his expenses finally exceeded the money advanced to him; for on Feb. 4, 1374, a further sum was paid to him, on this account, of 25l. 6s. 8d.[68] It was probably on this occasion that Chaucer met Petrarch at Padua, and learnt from him the story of Griselda, reproduced in the Clerkes Tale. Some critics prefer to think that Chaucer's assertions on this point are to be taken as imaginative, and that it was the Clerk, and not himself, who went to Padua; but it is clear that in writing the Clerkes Tale, Chaucer actually had a copy of Petrarch's Latin version before him; and it is difficult to see how he came by it unless he obtained it from Petrarch himself or by Petrarch's assistance. For further discussion of this point, see remarks on the Sources of the Clerkes Tale, in vol. iii., and the notes in vol. v.[69] We must, in any case, bear in mind the important influence which this mission to Italy, and a later one in 1378-9 to the same country, produced upon the development of his poetical writings. It may be convenient to note here that Petrarch resided chiefly at Arquà, within easy reach of Padua, in 1370-4. His death took place there on July 18, 1374, soon after Chaucer had returned home.
