However, granted there actually was an excrescence previously existing, which had been removed by the knife, of what nature was the said excrescence? It is scarcely possible, with Heindorf, to suppose the Satyriasis of Aristotle[132] to be intended here; with much greater probability _Schneider_ in his Greek Dictionary, under the word διονυσιακὸς (Dionysiac, connected with Dionysus) drew attention to the definition of _Galen_ (edit. Kühn XIX. p. 443.): διονυσίσκοι εἰσὶν ὀστώδεις ὑπεροχαὶ ἐγγὺς κροτάφων γιγνόμεναι. λέγονται δὲ κέρατα ἀπὸ τῶν κερασφορούντων ζάων κεκλημένα. (διονυσίσκοι are bony excrescences growing near the temples, and they are called horns, so named from the animals that carry horns). A passage of _Heliodorus_ (_Cocchi Ant., Graecorum chirurgici libri, e collect. Nicetae Florent._ 1754. fol., p. 125.) which _Oribasius, De fracturis_, has preserved, gives a slightly different account; it reads: Ὀστώδης ἐπίφυσις ἐν παντὶ μὲν γίγνεται μέρει τοῦ σώματος, πλεοναζόντως δὲ ἐν τῇ κεφαλῇ, μάλιστα δὲ πλησίον τῶν κροτάφων·Ὅταν δὲ δύο ἐπιφύσεις γένωνται πλησιάζουσαι τοῖς κροτάφοις, κέρατα ταῦτα τινες εἴωθασιν ὀνομάζειν, ἔνιοι δὲ _διονυσιακοὺς_ τοὺς οὕτω πεπονθότας ἀνθρώπους προσηγόρευσαν. (Bony outgrowth may occur in every part of the body, but pre-eminently on the head, and particularly near the temples. But when there are two such growths in the neighbourhood of the temples, some are wont to call them _horns_, but others name the patients so afflicted διονυσιακοὶ). Then follows the description of the outgrowth, and the method of its removal by excision. On this passage _Cocchi_ found an old marginal gloss from the hand of Nicotas (?), κέρατα μὲν λέγεται ἀπὸ τῆς τῶν κεράτων ἐκφύσεως, τῶν γιγνομένων τοῖς ἀλόγοις ζώοις. _Διονυσιακοὺς_ δὲ αὐτοὺς προσαγορεύουσιν, ἀπὸ τῆς πρὸς τὸν θεὸν ἐμφερείας _ὡς αὐτός_ φησιν ἐν τοῖς χειρουργουμένοις,—(they are called horns from the growth of the horns that appear on the lower animals. And they name them διονυσιακοὶ from the likeness to the god Dionysus, as he says himself, in the carved figures),—which on the whole confirms the statement of Heliodorus, though he (Cocchi) prefers, following this indication, to emend the passage of Galen also so as to read, διονυσιακοί, _οἷς_ ὀστώδεις ὑπεροχαὶ ἐγγὺς κροτάφων _γίγνονται_, (Dionysiaci, so they are called, i. e. those in whom bony excrescences grow near the temples). This much, that we should read διονυσιακοὶ for διονυσίσκοι, is evident, but whether the rest of the emendations are to be accepted may well be open to doubt, as the second clause of the sentence, “and they are called κέρατα (horns), so named from the animals that carry horns”, obviously implies that the term διονυσιακοὶ is used in reference not to the individual, but to the outgrowth. Schneider indeed agrees with the emendation of Cocchi, but has in error put Sarmentus in the place of Messius.
