The growth during the interval had been of three kinds, sometimes blended, sometimes kept apart. [Sidenote: _Editors, &c., of the_ Poetics.] The first kind consisted of translations, editions, and commentaries of and on the _Poetics_; the second, of abstract discussions of Poetry; the third, of more or less formal “Arts” not very different from Trissino’s own. The first class produced later, in the work of Castelvetro, a contribution of almost the first importance to the History and to the Art of Criticism; and it could not but exercise a powerful influence. It belongs, however, in all but its most prominent examples (such as that just referred to, which will be fully discussed in the next chapter), rather to monographers on Aristotle than to general historians of Criticism, inasmuch as it is mainly parasitic. [Sidenote: _Pazzi._] Before any book of original critical importance later than Trissino’s had been issued, in 1536,[57] Alessandro de’ Pazzi published a Latin translation of the _Poetics_, which for some time held the position of standard, and a dozen years later came three important works on the book—Robortello’s edition of 1548, Segni’s Italian translation of 1549, and Maggi’s edition of 1550—all showing the attention and interest which the subject was exciting, while, still before the later “Divisions” of Trissino appeared, Vettori in 1560 added his edition, of greater importance than any earlier one. Long before this the book had become a regular subject of lectures. Of these writers Robortello, and still more Vettori (“Victorius”), were of the greatest service to the text; Maggi, who was assisted by Lombardi, to the discussion of the matter.[58] ----- Footnote 55: Spingarn, p. 102. Footnote 56: The discussion occupies nearly four quarto pages, ii. 127-130. Trissino, of course, does not neglect Quintilian’s handling of the subject in _Inst._, vi. 3, and he quotes modern as well as ancient examples. Footnote 57: Dolce had translated the _Ars Poetica_ of Horace into Italian the year before. Footnote 58: Mr Spingarn has extracted from MS., and published as an appendix to his book, an interesting review of these commentators and others, by Leonardo Salviati, a successor of theirs in 1586, and too famous in the Tasso controversy. -----
