An excerpt from the Introduction to Boethius: § 1. Date Of The Work. In my introductory remarks to the Legend of Good Women, I refer to the close connection that is easily seen to subsist between Chaucer's translation of Boethius and his Troilus and Criseyde. All critics seem now to agree in placing these two works in close conjunction, and in making the prose work somewhat the earlier of the two; though it is not at all unlikely that, for a short time, both works were in hand together. It is also clear that they were completed before the author commenced the House of Fame, the date of which is, almost certainly, about 1383-4. Dr. Koch, in his Essay on the Chronology of Chaucer's Writings, proposes to date 'Boethius' about 1377-8, and 'Troilus' about 1380-1. It is sufficient to be able to infer, as we can with tolerable certainty, that these two works belong to the period between 1377 and 1383. And we may also feel sure that the well-known lines to Adam, beginning- 'Adam scriveyn, if ever it thee befalle Boece or Troilus to wryten newe'- were composed at the time when the fair copy of Troilus had just been finished, and may be dated, without fear of mistake, in 1381-3. It is not likely that we shall be able to determine these dates within closer limits; nor is it at all necessary that we should be able to do so.... * * * * * An excerpt from the Introduction to Troilus: § 1. Date Of The Work. The probable date is about 1380-2, and can hardly have been earlier than 1379 or later than 1383. No doubt it was in hand for a considerable time. It certainly followed close upon the translation of Boethius; see above. § 2. Sources Of The Work. The chief authority followed by Chaucer is Boccaccio's poem named "Il Filostrato", in 9 Parts or Books of very variable length, and composed in ottava rima, or stanzas containing eight lines each. I have used the copy in the Opere Volgari di G. Boccaccio; Firenze, 1832. Owing to the patient labours of Mr. W. M. Rossetti, who has collated the "Filostrato" with the "Troilus" line by line, and published the results of his work for the Chaucer Society in 1875, we are able to tell the precise extent to which Chaucer is indebted to Boccaccio for this story....
