In the introduction to his magisterial commentary on Historia animalium Books 8–9,Footnote 1 in the Aristoteles Werke in deutscher Übersetzung series, Stefan Schnieders presents ancient (that is, Hellenistic and Alexandrian) evidence for Historia animalium 7(8) having been considered the seventh book of this work.Footnote 2 He goes on to argue, however, in agreement with Kullmann and against Balme, that nevertheless Theodore Gaza was right to change the order.Footnote 3 The nature of these arguments, and whether they succeed, will not concern me here. Rather, I want to point to two texts that provide further evidence for Historia animalium 7(8) being considered the seventh book in antiquity—texts which Schnieders does not mention and which have not been discussed in connection with the order of the books of the Historia animalium. They both come from discussions of a word or set of words in Iliad Book 21.Footnote 4
I. P.OXY. 221, COL. X 11–14
The first text is a passage in P.Oxy. 221 (c. a.d. 100), the papyrus remains of an anonymous commentary on Iliad Book 21.Footnote 5 It concerns the phrase ἐγχέλυές τε καὶ ἰχθύες, which appears twice in Iliad Book 21 (203 and 353), and which troubled ancient Homeric scholars.Footnote 6 Why, they wondered, did Homer distinguish eels and fish given that eels are a kind of fish?Footnote 7 The author of the commentary presents a number of solutions to the problem, one set of them from Aristotle. The first of these (which mentions Aristotle's name but not the work from which it comes) is a near verbatim quotation of Hist. an. 6.16.570a3–17, on eel generation. (The author considers this relevant, because he believes that, if eels are the product of spontaneous generation, as Aristotle claims, this would justify Homer having distinguished them from fish.) The second solution comes from Aristotle's Historia animalium Book 7(8) by way of Didymus of Alexandria (second half of the first century b.c.) (P.Oxy. 221, col. X 11–14):Footnote 8
ἐν δὲ τῷ ζʹ φησὶν αὐτὸν λέ|γειν Δί̣δ̣υ̣μος ἀμαρτύρως ὅτι καὶ ἀλ|ληλοφάγον ἐστὶν καὶ ὅτι ζῇ ζʹ καὶ ηʹ | ἔτ̣η.
And Didymus claims without evidenceFootnote 9 that he [sc. Aristotle]Footnote 10 in [Historia animalium Book] 7 said that [eels] eat each other and live seven or eight years.
Now one could render this: ‘In [Book] 7, Didymus claims without evidence that he [sc. Aristotle] said’, etc., in which case the reference is to Book 7 of a lost work of Didymus (for instance his commentary on the Iliad). But I agree with Grenfell and Hunt, Van der Valk, Keaney and Montanari,Footnote 11 who take the ζʹ to be referring to Historia animalium Book 7(8).Footnote 12 Specifically—and this supports taking ζʹ to refer to the Historia animalium—Didymus is paraphrasing Hist. an. 7(8).2.592a23–5:
ζῶσι δ’ ἔνιαι ἐγχέλεις καὶ ἑπτὰ καὶ ὀκτὼ ἔτη. τροφῇ δὲ καὶ οἱ ποτάμιοι χρῶνται ἀλλήλους τ’ ἐσθίοντες καὶ βοτάνας καὶ ῥίζας, κἄν τι ἐν τῷ βορβόρῳ λάβωσιν.
Some eels live even seven or eight years. Now the river animals [sc. fish or eels] too get nourishment eating each other as well as plants and roots, and anything they might find in the mire.
This first sentence comes at the end of Aristotle's discussion of eels. οἱ ποτάμιοι in the second sentence likely refers to river fish, though Didymus clearly took it to be a kind of eel.Footnote 13 But the important point is that he identified the passage as coming from Book 7.Footnote 14 Separate papyrus rolls of some of the books of the Historia animalium were likely circulating at this time, as well as collected excerpts of Aristotle's works on animals.Footnote 15 The author of the commentary on Iliad Book 21 was likely relying on two sources here: (1) for the quotation from Hist. an. 6.16 a papyrus roll of that entire book, or a compilation of excerpts from Aristotle's writings on animals that contained that passage; (2) a work of Didymus which quoted or more likely paraphrased Historia animalium Book 7(8) and which he identified as coming from Book 7.
II. PORPHYRY, HOMERIC QUESTIONS BOOK 1 (§8, PAGE 43.8–14 SODANO)Footnote 16
The relevant Homeric passage is Il. 21.126–7, which describes fish eating the corpse of Lycaon (who was killed by Achilles and tossed into the river Xanthus). Porphyry (third century a.d.) is discussing whether a disputed word in verse 126 should be ὑπαΐξει or ὑπαλύξει (and so whether a fish will dart or escape beneath the waves).Footnote 17 While appraising the case for ὑπαλύξει, and why a fish might escape beneath the waves, Porphyry remarks:
πολλοὺς δὲ αὐτῶν καὶ φωλεύειν κατὰ τοῦ βάθους διὰ τὴν αὐτὴν αἰτίαν ἱστορεῖ γὰρ καὶ ὁ Ἀριστοτέλης ἐν τῷ ζʹ Περὶ ζώων φύσεως⋅ ψυχροτάτη δ’ ἡ φρίκη, καὶ μάλιστα ἂν βόρειος ᾖ. γενόμενος δ’ ἐν τῷ βάθει τοῦ Λυκάονος ἔδεται τὸ λίπος.Footnote 18
Aristotle, in Book 7 of On the Nature of Animals, also reports that many of them [sc. fish] hide in the depths for the same reason [sc. mentioned earlier]: the rippling-water is quite cold, especially if it is northern. And while in the depths [the fish] will eat the fat of Lycaon.
This is almost certainly a reference to (but not a quotation from or even a paraphrase of) Hist. an. 7(8).15, which includes a lengthy discussion of fish hiding or hibernating, especially in winter (see 599b2–600a10). A couple of lines will suffice: ‘Many of the fish hide as well, most noticeably hippouros and korakinos in winter’ (φωλοῦσι δὲ πολλοὶ καὶ τῶν ἰχθύων, ἐπιφανέστατα δ’ ἵππουρος καὶ κορακῖνος τοῦ χειμῶνος, 599b2–3); and ‘most of them [sc. fish] hide in winter’ (τὰ μὲν οὖν πλεῖστα φωλεῖ τοῦ χειμῶνος, 599b27–8). Note too that this is an ancient variant of the title of the Historia animalium not mentioned by Schnieder in his discussion of titles attributed to the work in antiquity (n. 2), 99–102: Περὶ ζώων φύσεως.

My aim in this note was not to level a criticism against Schnieder for a serious omission but to supplement and support his excellent discussion by adding these two obscure texts to the evidence he presents.
