The poem is extant in nine MSS. It is attributed to Chaucer by Shirley in MS. 'Sh.,' and the internal evidence confirms this. There is a fairly good copy in MS. F., on which my edition of it is based. There is, further, an excellent _critical edition_ of this poem by Prof. Ten Brink, in _Essays on Chaucer_, Part II, p. 170 (Chaucer Soc.); this I carefully consulted after making my own copy, and I found that the differences were very slight. The least valuable MSS. seem to be Ff., Ph., and Lt. Omitting these, the MSS. may be divided into three sets, viz. A, Ba, and Bb, the two last going back to a common source B. These are: (A.)--Sh. Ha.; (Ba.)--F. B.; (Bb.)--Tn. Trin. See Koch, in Anglia, iv. b. 96. In this poem we have the earliest example, in English, of the famous 7-line stanza. § 20. III. THE BOOK OF THE DUCHESSE. Here we are on firm ground. The genuineness of this poem has never been doubted. It is agreed that the word _Whyte_ in l. 948, which is given as the name of the lady lately dead, is a translation of _Blanche_, and that the reference is to the wife of the Duke of Lancaster (John of Gaunt), who died Sept. 12, 1369, at the age of twenty-nine, her husband being then of the same age. As the poem would naturally be written soon after this event, the date must be near the end of 1369. In fact, John of Gaunt married again in 1372, whereas he is represented in the poem as being inconsolable. Chaucer's own testimony, in the Legend of Good Women, l. 418, is that he made 'the deeth of Blaunche the Duchesse'; and again, in the Introduction to the Man of Law's Prologue, l. 57, that 'In youthe he made of Ceys and Alcion.' In 1369, Chaucer was already twenty-nine years of age (taking the year of his birth to be 1340, not 1328), which is rather past the period of youth; and the fact that he thus mentions 'Ceys and Alcion' as if it were the name of an independent poem, renders it almost certain that such was once the case. He clearly thought it too good to be lost, and so took the opportunity of inserting it in a more ambitious effort. The original 'Ceys and Alcion' evidently ended at l. 220; where it began, we cannot say, for the poem was doubtless revised and somewhat altered. Ll. 215, 216 hint that a part of it was suppressed. The two subjects were easily connected, the sorrow of Alcyone for the sudden and unexpected loss of her husband being the counterpart of the sorrow of the duke for the loss of his wife. The poem of 'Ceys and Alcion' shews Chaucer under the influence of Ovid, just as part of his Complaint to Pity was suggested by Statius; but in the later part of the poem of the Book of the Duchesse we see him strongly influenced by French authors, chiefly Guillaume de Machault and the authors of Le Roman de la Rose. His familiarity with the latter poem (as pointed out in the notes) is such as to prove that he had already been previously employed in making his translation of that extremely lengthy work, and possibly
