Yet to the historian of criticism he has a singular interest, because of that position of origin which has been noted. Cicero and Pliny in their libraries were in a position to do much the same thing; had, as we shall see, a kind of dim velleity of doing it now and then, but did it not. Athenæus, if he had cared less for cooks and courtesans, more for literature; Aulus Gellius and Macrobius, if mere philology on the one hand, and mere folk-lore and mythology on the other, had not drawn them aside, would probably have anticipated him. But no one actually has; none has applied to the library or its prose division the process which goes to the making of a _catalogue raisonné_ in painting. No doubt Photius leaves a good deal to be done, independently of his silence on poetry and drama. His comparison is so limited as to be almost non-existent; it is much if he can compare Heliodorus, Iamblichus, and Achilles Tatius in reference to the treatment of matters erotic; Ctesias and Herodotus, on the score of resisting, or succumbing to, story-telling digression. But even in this there is the germ, the rudiment, of the great Comparative Method. So again the other great Lamp of Criticism, the historical estimate, still has its shutter drawn for him. A vague distinction between the ἀρχαῖοι and the moderns is indeed not uncommon; but we have, so far as I have noticed, no distinct line drawn between the two, and both are huddled and jumbled together. Photius has not yet risen to that highest conception of criticism which involves the “grasping” of each author in his complete self, and the placing of him in the general literary map or genealogy (whichever phase may be preferred) of the world. And lastly, the silly old etiquette of silence about Latin still seems to weigh, if unconsciously, on him. He does indeed allude to the birth-year of Virgil. In his notices of historians of Rome he necessarily has to mention some Roman matters, and he mentions that Cicero was slain while reading the _Medea_. But my memory, assisted by Bekker’s excellent index, traces no critical remark, comparative or independent, about any great Latin writer, and nothing more than the barest mention of one or two by name. Yet, with all these drawbacks, the niche we have indicated is securely his, though he has scarcely yet been established in it.[267] Footnote 267: There is in Photius a later notice of Isocrates, in connection with others of the usual set of Attic orators; and these are chiefly interesting for some references to the literary historian Cæcilius, referred to by Longinus, and to Longinus himself as “the critic who flourished under Claudius” (predecessor of Aurelian), “and took great share in the struggle of Zenobia, queen of the Osrhoeni.” But the criticism on Demosthenes referred to can hardly be that of the Περὶ Ὕψους.
