There is another point also which I conceive to be proved by what we hear about Aristophanes. He (or Kallimachus before him) introduced a new order or distribution of his own — the Trilogies — founded on the analogy of the dramatic Didaskalies. This shows that the Platonic dialogues were not received into the library in any canonical or exclusive order of their own, or in any interdependence as first, second, third, &c., essential to render them intelligible as a system. Had there been any such order, Kallimachus and Aristophanes would no more have altered it, than they would have transposed the order of the books in the Republic and Leges. The importance of what is here observed will appear presently, when we touch upon the theory of Schleiermacher.
Other libraries and literary centres, besides Alexandria, in which spurious Platonic works might get footing.
The distributive arrangement, proposed or sanctioned by Aristophanes, applied (as I have already remarked) to the materials in the Alexandrine library only. But this library, though it was the most conspicuous portion, was not the whole, of the Grecian literary aggregate. There were other great regal libraries (such as those of the kings of Pergamus and the Seleukid kings[39]) commenced after the Alexandrine library had already attained importance, and intended to rival it: there was also an active literary and philosophising class, in various Grecian cities, of which Athens was the foremost, but in which Rhodes, Kyrênê, and several cities in Asia Minor, Kilikia, and Syria, were included: ultimately the cultivated classes at Rome, and the Western Hellenic city of Massalia, became comprised in the number. Among this widespread literary public, there were persons who neither knew nor examined the Platonic school or the Alexandrine library, nor investigated what title either of them had to furnish a certificate authenticating the genuine works of Plato. It is not certain that even the great library at Pergamus, begun nearly half a century after that of Alexandria, had any such initiatory agent as Demetrius Phalereus, able as well as willing to go to the fountain-head of Platonism at Athens: nor could the kings of Pergamus claim aid from Alexandria, with which they were in hostile rivalry, and from which they were even forbidden (so we hear) to purchase papyrus. Under these circumstances, it is quite possible that spurious Platonic writings, though they obtained no recognition in the Alexandrine library, might obtain more or less recognition elsewhere, and pass under the name of Plato. To a certain extent, such was the case. There existed some spurious dialogues at the time when Thrasyllus afterwards formed his arrangement.
[39] The library of Antiochus the Great or of his predecessor, is mentioned by Suidas, Εὐφορίων. Euphorion was librarian of it, seemingly about 230-220 B.C. See Clinton, Fast. Hell. B.C. 221.
Galen states (Comm. in Hippok. De Nat. Hom. vol. xv. p. 105, Kühn) that the forgeries of books, and the practice of tendering books for sale under the false names of celebrated authors, did not commence until the time when the competition between the kings of Egypt and the kings of Pergamus for their respective libraries became vehement. If this be admitted, there could have been no forgeries tendered at Alexandria until after the commencement of the reign of Euergetes (B.C. 247-222): for the competition from Pergamus could hardly have commenced earlier than 230 B.C. In the times of Soter and Philadelphus, there would be no such forgeries tendered. I do not doubt that such forgeries were sometimes successfully passed off: but I think Galen does not take sufficient account of the practice (mentioned by himself) at the Alexandrine library, to keep faithful record of the person and quarter from whence each book had been acquired.
Other critics, besides Aristophanes, proposed different arrangements of the Platonic dialogues.
Moreover the distribution made by Aristophanes of the Platonic dialogues into Trilogies, and the order of priority which he established among them was by no means universally accepted. Some rejected altogether the dramatic analogy of Trilogies as a principle of distribution. They arranged the dialogues into three classes:[40] 1. The Direct, or purely dramatic. 2. The Indirect, or narrative (diegematic). 3. The Mixed — partly one, partly the other. Respecting the order of priority, we read that while Aristophanes placed the Republic first, there were eight other arrangements, each recognising a different dialogue as first in order; these eight were, Alkibiades I., Theagês, Euthyphron, Kleitophon, Timæus, Phædrus, Theætêtus, Apology. More than one arrangement began with the Apology. Some even selected the Epistolæ as the proper commencement for studying Plato’s works.[41]
[40] Diog. L. iii. 49. Schöne, in his commentary on the Protagoras (pp. 8-12), lays particular stress on this division into the direct or dramatic, and indirect or diegematic. He thinks it probable, that Plato preferred one method to the other at different periods of life: that all of one sort, and all of the other sort, come near together in time.
