§ 6. It has been observed that, whilst Chaucer carefully read and made very good use of two of Boccaccio's works, viz. Il Filostrato and Il Teseide, he nowhere mentions Boccaccio by name; and this has occasioned some surprise. But we must not apply modern ideas to explain medieval facts, as is so frequently done. When we consider how often MSS. of works by known authors have no author's name attached to them, it becomes likely that Chaucer obtained manuscript copies of these works unmarked by the author's name; and though he must doubtless have been aware of it, there was no cogent reason why he should declare himself indebted to one in whom Englishmen were, as yet, quite uninterested. Even when he refers to Petrarch in the Clerk's Prologue (E 27-35), he has to explain who he was, and to inform readers of his recent death. In those days, there was much laxity in the mode of citing authors.
§ 7. It will help us to understand matters more clearly, if we further observe the haphazard manner in which quotations were often made. We know, for example, that no book was more accessible than the Vulgate version of the Bible; yet it is quite common to find the most curious mistakes made in reference to it. The author of Piers Plowman (B. text, iii. 93-95) attributes to Solomon a passage which he quotes from Job, and (B. vii. 123) to St. Luke, a passage from St. Matthew; and again (B. vi. 240) to St. Matthew, a passage from St. Luke. Chaucer makes many mistakes of a like nature; I will only cite here his reference to Solomon (Cant. Tales, A 4330), as the author of a passage in Ecclesiasticus. Even in modern dictionaries we find passages cited from 'Dryden' or 'Bacon' at large, without further remark; as if the verification of a reference were of slight consequence. This may help to explain to us the curious allusion to _Zanzis_ as being the author of a passage which Chaucer must have known was from his favourite Ovid (see note to Troil. iv. 414), whilst he was, at the same time, well aware that Zanzis was not a poet, but a painter (Cant. Tales, C 16); however, in this case we have probably to do with a piece of our author's delicious banter, since he adds that Pandarus was speaking 'for the nonce.'
