Headword: Μῆνιγξ
Adler number: mu,952
Translated headword: dura mater; meninx
Vetting Status: high
Translation:
[The term for] a membrane covering the brain. With the so-called meningophylax ["meninx-guard"] covering the membrane, the living tissue becomes insensate and unmoving.[1] [Note] that the senses beginning from the brain proceed through the nerves up to the sensory organs. Therefore the sense of hearing proceeds as far as the base of the ears, which they call "meninges". There is a nerve provided with pores proceeding from the brain, in the pore [of which] there is an optic air-flow. There is, then, a certain air intercepted in the cavity of the ear which is combined with the meninx and the membrane. This air, then, receiving noises from the outside air and itself having an ability to conduct sound, transmits the sounds through itself into the meninx. It goes on from the rather wide passageway of the meninx. One should not consider this to be only air, even if it is of the same substance, and indivisible, as if it were always one and the same in number; rather, it is divisible into parts and generable just like any other physical component of man. It receives directly the impacts of the air outside. Therefore the ear also experiences loud sounds, when the air outside is thrust violently and with force it thrusts this similar air in the ears and often disperses it. And on account of the circumstantial functions, the immersions in waters, this air is built into its position in the sensory organ. Because of this nature also made the cavities of the ears spiral-shaped, so that something could not easily enter and strike the meninx.[2]
Greek Original:
Μῆνιγξ: ὑμὴν τὸν ἐγκέφαλον σκέπων. τοῦ δὲ καλουμένου μηνιγγοφύλακος ἐπιτεθέντος τῇ μήνιγγι, ἀναίσθητον τὸ ζῷον γίνεται καὶ ἀκίνητον. ὅτι αἱ αἰσθήσεις ἀπὸ τοῦ ἐγκεφάλου ἀρχόμεναι διὰ τῶν νεύρων ἄχρι τῶν αἰσθητηρίων προί̈ασι. πρόεισιν οὖν καὶ ἡ ἀκουστικὴ δύναμις μέχρι τῆς ῥίζης τῶν ὤτων, ἃς καλοῦσι μήνιγγας. ἔστι δὲ νεῦρον ἀπὸ τοῦ ἐγκεφάλου προϊὸν πεποροποιημένον: ἐν ᾧ πόρῳ ἐστὶ τὸ ὀπτικὸν πνεῦμα. ἔστιν οὖν ἀπειλημμένος τις ἀὴρ ἐν τῷ κοιλώματι τῆς ἀκοῆς, συμφυὴς ὢν τῇ μήνιγγι καὶ τῷ ὑμένι. οὗτος οὖν ὁ ἀὴρ δεχόμενος ἐκ τοῦ ἔξωθεν ἀέρος τοὺς ψόφους, ἔχων καὶ αὐτὸς τὴν διηχῆ δύναμιν δι' ἑαυτοῦ εἰς τὴν μήνιγγα διαπορθμεύει τοὺς ψόφους. πρόεισι δ' ἀπὸ πλατυτέρου πόρου τῆς μήνιγγος. οὐ δεῖ δὲ νομίζειν τοῦτο μόνον ἀέρα, εἰ καὶ συμφυής ἐστιν, ἤδη καὶ ἄφθαρτον εἶναι, ὡς ἀεὶ ἕνα καὶ τὸν αὐτὸν τῷ ἀριθμῷ ὄντα: ἀλλ' ἔστι κατὰ μέρη φθαρτὸς καὶ γεννητὸς ὥσπερ καὶ τὸ ἄλλο τοῦ ἀνθρώπου σῶμα. ἀμέσως δὲ δέχεται τὰς τοῦ ἔξωθεν ἀέρος προσβολάς. διὸ καὶ ὑπὸ τῶν μεγάλων ψόφων πάσχει ἡ ἀκοή, τοῦ ἔξωθεν ἀέρος σφοδρῶς ὠθουμένου καὶ τῇ βίᾳ ὠθοῦντος τὸν ἐν τοῖς ὠσὶ συμφυᾶ τοῦτον ἀέρα καὶ πολλάκις διασκεδαννύντος αὐτόν. καὶ διὰ τὰς περιστατικὰς ἐνεργείας, ἤτοι τὰς ἐν τοῖς ὕδασι καταδύσεις, ἐγκατῳκοδόμηται οὗτος ὁ ἀὴρ εἰς φυλακὴν τοῦ αἰσθητηρίου. διὰ τοῦτο καὶ ἑλικοειδεῖς ἐποίησεν ἡ φύσις τοὺς πόρους τῶν ὤτων, ἵνα μὴ ῥᾳδίως εἰσέρχηταί τι καὶ πλήξῃ τὴν μήνιγγα.
Notes:
[1] John Philoponus, On Aristotle's De anima 19.8-11 Hayduck. The 'meningophylax' is not another anatomical term but describes an aspect of human medical intervention: either 'a metallic protector to prevent injury to the meninx in operations on the skull' (LSJ), or a dressing offering a simpler sort of protection.
