Plato, Timaeus 73a–76e: Marrow, bones, flesh and sinews; the head, hair and nails

Timaeus describes how the gods made marrow from the best triangles to bind the soul to the body, and divided it into the brain, the spinal marrow and the rest, and how they formed the bones, the flesh and the sinews. The head was made of a very thin bone and covered with a little flesh, to leave the senses keen, and the skull was formed round the brain. He says that the gods gave humans the skin as a protection, and from it hair and nails, and the thickest skin protecting the nerves, in expectation of the future creatures that would need them. He describes the shaping of the limbs, in which the thigh and the foot and the hand are set to bear weight and to work.

ΤΙ. τὴν ἐσομένην ἐν ἡμῖν ποτῶν καὶ ἐδεστῶν ἀκολασίαν ᾔδεσαν οἱ συντιθέντες ἡμῶν τὸ γένος, καὶ ὅτι τοῦ μετρίου καὶ ἀναγκαίου διὰ μαργότητα πολλῷ χρησοίμεθα πλέονι· ἵνʼ οὖν μὴ φθορὰ διὰ νόσους ὀξεῖα γίγνοιτο καὶ ἀτελὲς τὸ γένος εὐθὺς τὸ θνητὸν τελευτῷ, ταῦτα προορώμενοι τῇ τοῦ περιγενησομένου πώματος ἐδέσματός τε ἕξει τὴν ὀνομαζομένην κάτω κοιλίαν ὑποδοχὴν ἔθεσαν, εἵλιξάν τε πέριξ τὴν τῶν ἐντέρων γένεσιν, ὅπως μὴ ταχὺ διεκπερῶσα ἡ τροφὴ ταχὺ πάλιν τροφῆς ἑτέρας δεῖσθαι τὸ σῶμα ἀναγκάζοι, καὶ παρέχουσα ἀπληστίαν, διὰ γαστριμαργίαν ἀφιλόσοφον καὶ ἄμουσον πᾶν ἀποτελοῖ τὸ γένος, ἀνυπήκοον τοῦ θειοτάτου τῶν παρʼ ἡμῖν. τὸ δὲ ὀστῶν καὶ σαρκῶν καὶ τῆς τοιαύτης φύσεως πέρι πάσης ὧδε ἔσχεν. τούτοις σύμπασιν ἀρχὴ μὲν ἡ τοῦ μυελοῦ γένεσις· οἱ γὰρ τοῦ βίου δεσμοί, τῆς ψυχῆς τῷ σώματι συνδουμένης, ἐν τούτῳ διαδούμενοι κατερρίζουν τὸ θνητὸν γένος· αὐτὸς δὲ ὁ μυελὸς γέγονεν ἐξ ἄλλων. τῶν γὰρ τριγώνων ὅσα πρῶτα ἀστραβῆ καὶ λεῖα ὄντα πῦρ τε καὶ ὕδωρ καὶ ἀέρα καὶ γῆν διʼ ἀκριβείας μάλιστα ἦν παρασχεῖν δυνατά, ταῦτα ὁ θεὸς ἀπὸ τῶν ἑαυτῶν ἕκαστα γενῶν χωρὶς ἀποκρίνων, μειγνὺς δὲ ἀλλήλοις σύμμετρα, πανσπερμίαν παντὶ θνητῷ γένει μηχανώμενος, τὸν μυελὸν ἐξ αὐτῶν ἀπηργάσατο, καὶ μετὰ ταῦτα δὴ φυτεύων ἐν αὐτῷ κατέδει τὰ τῶν ψυχῶν γένη, σχημάτων τε ὅσα ἔμελλεν αὖ σχήσειν οἷά τε καθʼ ἕκαστα εἴδη, τὸν μυελὸν αὐτὸν τοσαῦτα καὶ τοιαῦτα διῃρεῖτο σχήματα εὐθὺς ἐν τῇ διανομῇ τῇ κατʼ ἀρχάς. καὶ τὴν μὲν τὸ θεῖον σπέρμα οἷον ἄρουραν μέλλουσαν ἕξειν ἐν αὑτῇ περιφερῆ πανταχῇ πλάσας ἐπωνόμασεν τοῦ μυελοῦ ταύτην τὴν μοῖραν ἐγκέφαλον, ὡς ἀποτελεσθέντος ἑκάστου ζῴου τὸ περὶ τοῦτʼ ἀγγεῖον κεφαλὴν γενησόμενον· ὃ δʼ αὖ τὸ λοιπὸν καὶ θνητὸν τῆς ψυχῆς ἔμελλε καθέξειν, ἅμα στρογγύλα καὶ προμήκη διῃρεῖτο σχήματα, μυελὸν δὲ πάντα ἐπεφήμισεν, καὶ καθάπερ ἐξ ἀγκυρῶν βαλλόμενος ἐκ τούτων πάσης ψυχῆς δεσμοὺς περὶ τοῦτο σύμπαν ἤδη τὸ σῶμα ἡμῶν ἀπηργάζετο, στέγασμα μὲν αὐτῷ πρῶτον συμπηγνὺς περὶ ὅλον ὀστέινον. τὸ δὲ ὀστοῦν συνίστησιν ὧδε. γῆν διαττήσας καθαρὰν καὶ λείαν ἐφύρασε καὶ ἔδευσεν μυελῷ, καὶ μετὰ τοῦτο εἰς πῦρ αὐτὸ ἐντίθησιν, μετʼ ἐκεῖνο δὲ εἰς ὕδωρ βάπτει, πάλιν δὲ εἰς πῦρ, αὖθίς τε εἰς ὕδωρ· μεταφέρων δʼ οὕτω πολλάκις εἰς ἑκάτερον ὑπʼ ἀμφοῖν ἄτηκτον ἀπηργάσατο.

Those who were constructing our kind were aware of the incontinence that would reside in us in respect of drinks and meats, and how that because of our greed we would consume far more than what was moderate and necessary; wherefore, lest owing to maladies swift destruction should overtake them, and the mortal kind, while still incomplete, come straightway to a complete end,—foreseeing this, the Gods set the “abdomen,” as it is called, to serve as a receptacle for the holding of the superfluous meat and drink; and round about therein they coiled the structure of the entrails, to prevent the food from passing through quickly and thereby compelling the body to require more food quickly, and causing insatiate appetite, whereby the whole kind by reason of its gluttony would be rendered devoid of philosophy and of culture, and disobedient to the most divine part we possess. As regards the bones and the flesh and all such substances the position was this. All these had their origin in the generation of the marrow. For it was in this that the bonds of life by which the Soul is bound to the body were fastened, and implanted the roots of the mortal kind; but the marrow itself was generated out of other elements. Taking all these primary triangles which, being unwarped and smooth, were best able to produce with exactness fire and water and air and earth, God separated them, each apart from his own kind, and mixing them one with another in due proportion, He fashioned therefrom the marrow, devising it as a universal seed-stuff for every mortal kind. Next, He engendered therein the various kinds of Soul and bound them down; and He straightway divided the marrow itself, in His original division, into shapes corresponding in their number and their nature to the number and the nature of the shapes which should belong to the several kinds of Soul. And that portion of the marrow which was intended to receive within itself, as it were into a field, the divine seed He molded in the shape of a perfect globe and bestowed on it the name of “brain,” purposing that, when each living creature should be completed, the vessel surrounding this should be called the “head.” But that portion which was to contain the other and mortal part of the Soul He divided into shapes that were at once rounded and elongated, and all these He designated “marrow”; and from these, as from anchors, He cast out bands of the Whole Soul, and around this He finally wrought the whole of this body of ours, when He had first built round about it for a shelter a framework all of bone. And bone He compounded in this wise. Having sifted earth till it was pure and smooth, He kneaded it and moistened it with marrow; then He placed it in fire, and after that dipped it in water, and from this back to fire, and once again in water; and by thus transferring it many times from the one element to the other He made it so that it was soluble by neither.

ΤΙ. καταχρώμενος δὴ τούτῳ περὶ μὲν τὸν ἐγκέφαλον αὐτοῦ σφαῖραν περιετόρνευσεν ὀστεΐνην, ταύτῃ δὲ στενὴν διέξοδον κατελείπετο· καὶ περὶ τὸν διαυχένιον ἅμα καὶ νωτιαῖον μυελὸν ἐξ αὐτοῦ σφονδύλους πλάσας ὑπέτεινεν οἷον στρόφιγγας, ἀρξάμενος ἀπὸ τῆς κεφαλῆς, διὰ παντὸς τοῦ κύτους. καὶ τὸ πᾶν δὴ σπέρμα διασῴζων οὕτως λιθοειδεῖ περιβόλῳ συνέφραξεν, ἐμποιῶν ἄρθρα, τῇ θατέρου προσχρώμενος ἐν αὐτοῖς ὡς μέσῃ ἐνισταμένῃ δυνάμει, κινήσεως καὶ κάμψεως ἕνεκα. τὴν δʼ αὖ τῆς ὀστεΐνης φύσεως ἕξιν ἡγησάμενος τοῦ δέοντος κραυροτέραν εἶναι καὶ ἀκαμπτοτέραν, διάπυρόν τʼ αὖ γιγνομένην καὶ πάλιν ψυχομένην σφακελίσασαν ταχὺ διαφθερεῖν τὸ σπέρμα ἐντὸς αὑτῆς, διὰ ταῦτα οὕτω τὸ τῶν νεύρων καὶ τὸ τῆς σαρκὸς γένος ἐμηχανᾶτο, ἵνα τῷ μὲν πάντα τὰ μέλη συνδήσας ἐπιτεινομένῳ καὶ ἀνιεμένῳ περὶ τοὺς στρόφιγγας καμπτόμενον τὸ σῶμα καὶ ἐκτεινόμενον παρέχοι, τὴν δὲ σάρκα προβολὴν μὲν καυμάτων, πρόβλημα δὲ χειμώνων, ἔτι δὲ πτωμάτων οἷον τὰ πιλητὰ ἔσεσθαι κτήματα, σώμασιν μαλακῶς καὶ πρᾴως ὑπείκουσαν, θερμὴν δὲ νοτίδα ἐντὸς ἑαυτῆς ἔχουσαν θέρους μὲν ἀνιδίουσαν καὶ νοτιζομένην ἔξωθεν ψῦχος κατὰ πᾶν τὸ σῶμα παρέξειν οἰκεῖον, διὰ χειμῶνος δὲ πάλιν αὖ τούτῳ τῷ πυρὶ τὸν προσφερόμενον ἔξωθεν καὶ περιιστάμενον πάγον ἀμυνεῖσθαι μετρίως. ταῦτα ἡμῶν διανοηθεὶς ὁ κηροπλάστης, ὕδατι μὲν καὶ πυρὶ καὶ γῇ συμμείξας καὶ συναρμόσας, ἐξ ὀξέος καὶ ἁλμυροῦ συνθεὶς ζύμωμα ὑπομείξας αὐτοῖς, σάρκα ἔγχυμον καὶ μαλακὴν συνέστησεν· τὴν δὲ τῶν νεύρων φύσιν ἐξ ὀστοῦ καὶ σαρκὸς ἀζύμου κράσεως μίαν ἐξ ἀμφοῖν μέσην δυνάμει συνεκεράσατο, ξανθῷ χρώματι προσχρώμενος. ὅθεν συντονωτέραν μὲν καὶ γλισχροτέραν σαρκῶν, μαλακωτέραν δὲ ὀστῶν ὑγροτέραν τε ἐκτήσατο δύναμιν νεῦρα· οἷς συμπεριλαβὼν ὁ θεὸς ὀστᾶ καὶ μυελόν, δήσας πρὸς ἄλληλα νεύροις, μετὰ ταῦτα σαρξὶν πάντα αὐτὰ κατεσκίασεν ἄνωθεν. ὅσα μὲν οὖν ἐμψυχότατα τῶν ὀστῶν ἦν, ὀλιγίσταις συνέφραττε σαρξίν, ἃ δʼ ἀψυχότατα ἐντός, πλείσταις καὶ πυκνοτάταις, καὶ δὴ κατὰ τὰς συμβολὰς τῶν ὀστῶν, ὅπῃ μήτινα ἀνάγκην ὁ λόγος ἀπέφαινεν δεῖν αὐτὰς εἶναι, βραχεῖαν σάρκα ἔφυσεν, ἵνα μήτε ἐμποδὼν ταῖς καμπαῖσιν οὖσαι δύσφορα τὰ σώματα ἀπεργάζοιντο, ἅτε δυσκίνητα γιγνόμενα, μήτʼ αὖ πολλαὶ καὶ πυκναὶ σφόδρα τε ἐν ἀλλήλαις ἐμπεπιλημέναι, διὰ στερεότητα ἀναισθησίαν ἐμποιοῦσαι, δυσμνημονευτότερα καὶ κωφότερα τὰ περὶ τὴν διάνοιαν ποιοῖεν.

This, then, He used, and fashioned thereof, by turning, a bony sphere round about the brain; and therein he left a narrow opening; and around the marrow of both neck and back He molded vertebrae of bone, and set them, like pivots, in a vertical row, throughout all the trunk, beginning from the head. And thus for preserving the whole seed He closed it in with a ring-fence of stony substance; and therein He made joints, using as an aid the power of the Other as an intermediary between them, for the sake of movement and bending. And inasmuch as He deemed that the texture of the bony substance was too hard and inflexible, and that if it were fired and cooled again it would decay and speedily destroy the seed within it, for these reasons He contrived the species known as sinew and flesh. He designed to bind all the limbs together by means of the former, which tightens and relaxes itself around the pivots, and thus cause the body to bend and stretch itself. And the flesh He designed to be a shield against the heat and a shelter against the cold; and, moreover, that in case of falls it should yield to the body softly and gently, like padded garments; and, inasmuch as it contains within it warm moisture, that it should supply in summer, by its perspiration and dampness, a congenial coolness over the exterior of the whole body, and contrariwise in winter defend the body sufficiently, by means of its fire, from the frost which attacks and surrounds it from without. Wherefore, with this intent, our Modeller mixed and blended together water and fire and earth, and compounding a ferment of acid and salt mixed it in therewith, and thus molded flesh full of sap and soft. And the substance of the sinews He compounded of a mixture of bone and unfermented flesh, forming a single substance blended of both and intermediate in quality, and he used yellow also for its coloring. Hence it is that the sinews have acquired a quality that is firmer and more rigid than flesh, but softer and more elastic than bone. With these, then, God enclosed the bones and marrow, first binding them one to another with the sinews, and then shrouding them all over with flesh. All the bones, then, that possessed most soul He enclosed in least flesh, but the bones which contained least soul with most and most dense flesh; moreover, at the junctions of the bones, except where reason revealed some necessity for its existence, He made but little flesh to grow, lest by hindering the flexions it should make the bodies unwieldy, because stiff in movement, or else through its size and density, when thickly massed together, it should produce insensitiveness, owing to its rigidity, and thereby cause the intellectual parts to be more forgetful and more obtuse.

ΤΙ. διὸ δὴ τό τε τῶν μηρῶν καὶ κνημῶν καὶ τὸ περὶ τὴν τῶν ἰσχίων φύσιν τά τε περὶ τὰ τῶν βραχιόνων ὀστᾶ καὶ τὰ τῶν πήχεων, καὶ ὅσα ἄλλα ἡμῶν ἄναρθρα, ὅσα τε ἐντὸς ὀστᾶ διʼ ὀλιγότητα ψυχῆς ἐν μυελῷ κενά ἐστιν φρονήσεως, ταῦτα πάντα συμπεπλήρωται σαρξίν· ὅσα δὲ ἔμφρονα, ἧττον—εἰ μή πού τινα αὐτὴν καθʼ αὑτὴν αἰσθήσεων ἕνεκα σάρκα οὕτω συνέστησεν, οἷον τὸ τῆς γλώττης εἶδος— τὰ δὲ πλεῖστα ἐκείνως· ἡ γὰρ ἐξ ἀνάγκης γιγνομένη καὶ συντρεφομένη φύσις οὐδαμῇ προσδέχεται πυκνὸν ὀστοῦν καὶ σάρκα πολλὴν ἅμα τε αὐτοῖς ὀξυήκοον αἴσθησιν. μάλιστα γὰρ ἂν αὐτὰ πάντων ἔσχεν ἡ περὶ τὴν κεφαλὴν σύστασις, εἴπερ ἅμα συμπίπτειν ἠθελησάτην, καὶ τὸ τῶν ἀνθρώπων γένος σαρκώδη ἔχον ἐφʼ ἑαυτῷ καὶ νευρώδη κρατεράν τε κεφαλὴν βίον ἂν διπλοῦν καὶ πολλαπλοῦν καὶ ὑγιεινότερον καὶ ἀλυπότερον τοῦ νῦν κατεκτήσατο. νῦν δὲ τοῖς περὶ τὴν ἡμετέραν γένεσιν δημιουργοῖς, ἀναλογιζομένοις πότερον πολυχρονιώτερον χεῖρον ἢ βραχυχρονιώτερον βέλτιον ἀπεργάσαιντο γένος, συνέδοξεν τοῦ πλείονος βίου, φαυλοτέρου δέ, τὸν ἐλάττονα ἀμείνονα ὄντα παντὶ πάντως αἱρετέον· ὅθεν δὴ μανῷ μὲν ὀστῷ, σαρξὶν δὲ καὶ νεύροις κεφαλήν, ἅτε οὐδὲ καμπὰς ἔχουσαν, οὐ συνεστέγασαν. κατὰ πάντα οὖν ταῦτα εὐαισθητοτέρα μὲν καὶ φρονιμωτέρα, πολὺ δὲ ἀσθενεστέρα παντὸς ἀνδρὸς προσετέθη κεφαλὴ σώματι. τὰ δὲ νεῦρα διὰ ταῦτα καὶ οὕτως ὁ θεὸς ἐπʼ ἐσχάτην τὴν κεφαλὴν περιστήσας κύκλῳ περὶ τὸν τράχηλον ἐκόλλησεν ὁμοιότητι, καὶ τὰς σιαγόνας ἄκρας αὐτοῖς συνέδησεν ὑπὸ τὴν φύσιν τοῦ προσώπου· τὰ δʼ ἄλλα εἰς ἅπαντα τὰ μέλη διέσπειρε, συνάπτων ἄρθρον ἄρθρῳ. τὴν δὲ δὴ τοῦ στόματος ἡμῶν δύναμιν ὀδοῦσιν καὶ γλώττῃ καὶ χείλεσιν ἕνεκα τῶν ἀναγκαίων καὶ τῶν ἀρίστων διεκόσμησαν οἱ διακοσμοῦντες ᾗ νῦν διατέτακται, τὴν μὲν εἴσοδον τῶν ἀναγκαίων μηχανώμενοι χάριν, τὴν δʼ ἔξοδον τῶν ἀρίστων· ἀναγκαῖον μὲν γὰρ πᾶν ὅσον εἰσέρχεται τροφὴν διδὸν τῷ σώματι, τὸ δὲ λόγων νᾶμα ἔξω ῥέον καὶ ὑπηρετοῦν φρονήσει κάλλιστον καὶ ἄριστον πάντων ναμάτων.

Wherefore the thighs and the shins and the region of the loins and the bones of the upper and lower arm, and all our other parts which are jointless, and all those bones which are void of intelligence within, owing to the small quantity of soul in the marrow—all these are abundantly supplied with flesh; but those parts which are intelligent are supplied less abundantly—except possibly where He so fashioned the flesh that it can of itself convey sensations, as is the case with the tongue; but most of these parts He made in the way described above. For the substance which is generated by necessity and grows up with us in no wise admits of quick perception coexisting with dense bone and abundant flesh. For if these characteristics were willing to consort together, then the structure of the head would have acquired them most of all, and mankind, crowned with a head that was fleshy and sinewy and strong, would have enjoyed a life that was twice (nay, many times) as long as our present life, and healthier, to boot, and more free from pain. But as it is, when the Constructors of our being were cogitating whether they should make a kind that was more long-lived and worse or more short-lived and better, they agreed that the shorter and superior life should by all means be chosen by all rather than the longer and inferior. Wherefore they covered the head closely with thin bone, but not with flesh and sinews, since it was also without flexions. For all these reasons, then, the head that was joined to the body in every man was more perceptive and more intelligent but less strong. It was on these grounds and in this way that God set the sinews at the bottom of the head round about the neck and glued them there symmetrically; and with these He fastened the extremities of the jaws below the substance of the face; and the rest of the sinews He distributed amongst all the limbs, attaching joint to joint. And those who fashioned the features of our mouth fashioned it with teeth and tongue and lips, even as it is fashioned now, for ends both necessary and most good, contriving it as an entrance with a view to necessary ends, and as an outlet with a view to the ends most good. For all that enters in and supplies food to the body is necessary; while the stream of speech which flows out and ministers to intelligence is of all streams the fairest and most good.

ΤΙ. τὴν δʼ αὖ κεφαλὴν οὔτε μόνον ὀστεΐνην ψιλὴν δυνατὸν ἐᾶν ἦν διὰ τὴν ἐν ταῖς ὥραις ἐφʼ ἑκάτερον ὑπερβολήν, οὔτʼ αὖ συσκιασθεῖσαν κωφὴν καὶ ἀναίσθητον διὰ τὸν τῶν σαρκῶν ὄχλον περιιδεῖν γιγνομένην· τῆς δὴ σαρκοειδοῦς φύσεως οὐ καταξηραινομένης λέμμα μεῖζον περιγιγνόμενον ἐχωρίζετο, δέρμα τὸ νῦν λεγόμενον. τοῦτο δὲ διὰ τὴν περὶ τὸν ἐγκέφαλον νοτίδα συνιὸν αὐτὸ πρὸς αὑτὸ καὶ βλαστάνον κύκλῳ περιημφιέννυεν τὴν κεφαλήν· ἡ δὲ νοτὶς ὑπὸ τὰς ῥαφὰς ἀνιοῦσα ἦρδε καὶ συνέκλεισεν αὐτὸ ἐπὶ τὴν κορυφήν, οἷον ἅμμα συναγαγοῦσα, τὸ δὲ τῶν ῥαφῶν παντοδαπὸν εἶδος γέγονε διὰ τὴν τῶν περιόδων δύναμιν καὶ τῆς τροφῆς, μᾶλλον μὲν ἀλλήλοις μαχομένων τούτων πλείους, ἧττον δὲ ἐλάττους. τοῦτο δὴ πᾶν τὸ δέρμα κύκλῳ κατεκέντει πυρὶ τὸ θεῖον, τρηθέντος δὲ καὶ τῆς ἰκμάδος ἔξω διʼ αὐτοῦ φερομένης τὸ μὲν ὑγρὸν καὶ θερμὸν ὅσον εἰλικρινὲς ἀπῄειν, τὸ δὲ μεικτὸν ἐξ ὧν καὶ τὸ δέρμα ἦν, αἰρόμενον μὲν ὑπὸ τῆς φορᾶς ἔξω μακρὸν ἐτείνετο, λεπτότητα ἴσην ἔχον τῷ κατακεντήματι, διὰ δὲ βραδυτῆτα ἀπωθούμενον ὑπὸ τοῦ περιεστῶτος ἔξωθεν πνεύματος πάλιν ἐντὸς ὑπὸ τὸ δέρμα εἱλλόμενον κατερριζοῦτο· καὶ κατὰ ταῦτα δὴ τὰ πάθη τὸ τριχῶν γένος ἐν τῷ δέρματι πέφυκεν, συγγενὲς μὲν ἱμαντῶδες ὂν αὐτοῦ, σκληρότερον δὲ καὶ πυκνότερον τῇ πιλήσει τῆς ψύξεως, ἣν ἀποχωριζομένη δέρματος ἑκάστη θρὶξ ψυχθεῖσα συνεπιλήθη. τούτῳ δὴ λασίαν ἡμῶν ἀπηργάσατο τὴν κεφαλὴν ὁ ποιῶν, χρώμενος μὲν αἰτίοις τοῖς εἰρημένοις, διανοούμενος δὲ ἀντὶ σαρκὸς αὐτὸ δεῖν εἶναι στέγασμα τῆς περὶ τὸν ἐγκέφαλον ἕνεκα ἀσφαλείας κοῦφον καὶ θέρους χειμῶνός τε ἱκανὸν σκιὰν καὶ σκέπην παρέχειν, εὐαισθησίας δὲ οὐδὲν διακώλυμα ἐμποδὼν γενησόμενον. τὸ δʼ ἐν τῇ περὶ τοὺς δακτύλους καταπλοκῇ τοῦ νεύρου καὶ τοῦ δέρματος ὀστοῦ τε, συμμειχθὲν ἐκ τριῶν, ἀποξηρανθὲν ἓν κοινὸν συμπάντων σκληρὸν γέγονεν δέρμα, τοῖς μὲν συναιτίοις τούτοις δημιουργηθέν, τῇ δὲ αἰτιωτάτῃ διανοίᾳ τῶν ἔπειτα ἐσομένων ἕνεκα εἰργασμένον. ὡς γάρ ποτε ἐξ ἀνδρῶν γυναῖκες καὶ τἆλλα θηρία γενήσοιντο, ἠπίσταντο οἱ συνιστάντες ἡμᾶς, καὶ δὴ καὶ τῆς τῶν ὀνύχων χρείας ὅτι πολλὰ τῶν θρεμμάτων καὶ ἐπὶ πολλὰ δεήσοιτο ᾔδεσαν, ὅθεν ἐν ἀνθρώποις εὐθὺς γιγνομένοις ὑπετυπώσαντο τὴν τῶν ὀνύχων γένεσιν. τούτῳ δὴ τῷ λόγῳ καὶ ταῖς προφάσεσιν ταύταις δέρμα τρίχας ὄνυχάς τε ἐπʼ ἄκροις τοῖς κώλοις ἔφυσαν.

Moreover, it was not possible to leave the head to consist of bare bone only, because of the excessive variations of temperature in either direction, due to the seasons; nor yet was it possible to allow it to be shrouded up, and to become, in consequence, stupid and insensitive owing to its burdensome mass of flesh. Accordingly, of the fleshy substance which was not being fully dried up a larger enveloping film was separated off, forming what is now called “skin.” And this, having united with itself because of the moisture round the brain and spreading, formed a vesture round about the head; and this was damped by the moisture ascending under the seams and closed down over the crown, being drawn together as it were in a knot; and the seams had all kinds of shapes owing to the force of the soul’s revolutions and of her food, being more in number when these are more in conflict with one another, and less when they are less in conflict. And the Deity kept puncturing all this skin round about with fire; and when the skin was pierced and the moisture flew out through it, all the liquid and heat that was pure went away, but such as was mixed with the substance whereof the skin also was composed was lifted up by the motion and extended far beyond the skin, being of a fineness to match the puncture; but since it was thrust back, because of its slowness, by the external air that surrounded it, it coiled itself round inside and rooted itself under the skin. Such, then, were the processes by which hair grew in the skin, it being a cord-like species akin to the skin but harder and denser owing to the constriction of the cold, whereby each hair as it separated off from the skin was chilled and constricted. Making use, then, of the causes mentioned our Maker fashioned the head shaggy with hair, purposing that, in place of flesh, the hair should serve as a light roofing for the part about the brain for safety’s sake, providing a sufficient shade and screen alike in summer and in winter, while proving no obstacle in the way of easy perception. And at the place in the fingers where sinew and skin and bone were interlaced there was formed a material blended of these three; and this when it was dried off became a single hard skin compounded of them all and whereas these were the auxiliary causes whereby it was fashioned, it was wrought by the greatest of causes, divine Purpose, for the sake of what should come to pass hereafter. For those who were constructing us knew that out of men women should one day spring and all other animals; and they understood, moreover, that many of these creatures would need for many purposes the help of nails; wherefore they impressed upon men at their very birth the rudimentary structure of finger-nails. Upon this account and with these designs they caused skin to grow into hair and nails upon the extremities of the limbs.
