Apollonius Paradoxographus, Historiae Mirabiles 49

“These things are worth knowing. Theophrastos has explained them in is work On Enthusiasm. For he says that music heals when suffering afflicts the soul and the body such as desperation, phobias, and the madnesses of belief which are more serious. For instrumental flute music, he continues, heals both hip pain and epilepsy.

Similarly is the power attributed to Aristoxenos the musician when he came—for he was getting a prophecy from the prophet of his sister Pasiphilê—for resuscitated a person in Thebes who was bewitched by the sound of a trumpet. For when he heard it he yelled out so much that he behaved indecently. If someone at any point even in war should blow the trumpet, then he should suffer much worse in his madness. So, he exposed him bit by bit to the flute—and, as one might say, he used this as an introduction for him to endure the trumpet as well.

The flute heals even if some part of the body is in pain. When the body is subject to flute music, let the instrumental music persist for five days at least. The toil will be surprisingly less on the first day and the second. This application of the flute treatment is common even elsewhere, but especially so in Thebes up to this day.”

49 ῎Αξια δ’ ἐστὶν ἐπιστάσεως [τὰ εἰρημένα.] <ἃ> Θεόφραστος ἐν τῷ περὶ ἐνθουσιασμοῦ ἐξεῖπεν. φησὶ γὰρ ἐκεῖνος τὴν μουσικὴν πολλὰ τῶν ἐπὶ ψυχὴν καὶ τὸ σῶμα γιγνομένων παθῶν ἰατρεύειν, καθάπερ λιποθυμίαν, φόβους καὶ τὰἐπὶ μακρὸν γιγνομένας τῆς διανοίας ἐκστάσεις. ἰᾶται γάρ, φησίν, ἡ καταύλησις καὶ ἰσχιάδα καὶ ἐπιληψίαν·

καθάπερ πρὸς ᾿Αριστόξενον τὸν μουσικὸν ἐλθόντα—χρήσασθαι αὐτὸν† τοῦ μαντίου τοῦ τῆς Πασιφίλης δαμωτι ἀδελφῆς † —λέγεται [τὸν μουσικὸν] καταστῆναί τινα ἐξιστάμενον ἐν Θήβαις ὑπὸ τὴν τῆς σάλπιγγος φωνήν· ἐπὶ τοσοῦτον γὰρ ἐβόησεν ἀκούων, ὥστε ἀσχημονεῖν· εἰ δέ ποτε καὶ πολεμικὸν σαλπίσειέ τις, πολὺ χεῖρον πάσχειν μαινόμενον. τοῦτον οὖν κατὰ μικρὸν  τῷ αὐλῷ προσάγειν, καὶ ὡς ἄν τις εἴποι ἐκ προσαγωγῆς ἐποίησεν καὶ τὴν σάλπιγγος φωνὴν ὑπομένειν.

θεραπεύει δὲ ἡ καταύλησις καὶ ἐάν τι μέρος τοῦ σώματος ἐν ἀλγήματι ὑπάρχῃ· καταυλουμένου τοῦ σώματος καταύλησις γιγνέσθω ἡμέρας ε′ ὡς ἐλάχιστα, καὶ εὐθέως τῇ πρώτῃ ἡμέρᾳ ἐλάττων ὁ πόνος γενήσεται καὶ τῇ δευτέρᾳ. τὸ δὲ γιγνόμενον διὰ τῆς καταυλήσεως ἐπιχωριάζει καὶ ἀλλαχῇ, μάλιστα δὲ ἐνΘήβαις μέχρι τῶν νῦν χρόνων.

Porphyry, On the Life of Pythagoras

30. “[Pythagoras] healed psychic and bodily sufferings with rhythm, songs, and incantations. He adapted these treatments to his companions, while he himself heard the harmony of everything because he could understand the unity of the spheres and the harmonies of the stars moving with them. It is not our nature to hear this in the least.”

30. κατεκήλει δὲ ῥυθμοῖς καὶ μέλεσι καὶ ἐπῳδαῖς τὰ ψυχικὰ πάθη καὶ τὰ σωματικά. καὶ τοῖς μὲν ἑταίροις ἡρμόζετο ταῦτα, αὐτὸς δὲ τῆς τοῦ παντὸς ἁρμονίας ἠκροᾶτο συνιεὶς τῆς καθολικῆς τῶν σφαιρῶν καὶ τῶν κατ’ αὐτὰς κινουμένων ἀστέρων ἁρμονίας, ἧς ἡμᾶς μὴ ἀκούειν διὰ σμικρότητα τῆς φύσεως.

32. “Diogenes says that Pythagoras encouraged all men to avoid ambition and lust for fame, because they especially inculcate envy, and also to stay away from large crowds. He used to convene gatherings at his house at dawn himself, accompanying his singing to the lyre and singing some ancient songs of Thales. And he also sang the songs of Hesiod and Homer, as many as appeared to calm his spirit. He would also dance some dances which he believed brought good mobility and health to the body. He used to take walks himself but not with a crowd, taking only two or three companions to shrines or groves, finding the most peaceful and beautiful places.”

32. Διογένης φησὶν ὡς ἅπασι μὲν παρηγγύα φιλοτιμίαν φεύγειν καὶ φιλοδοξίαν, ὥπερ μάλιστα φθόνον ἐργάζεσθαι, ἐκτρέπεσθαι δὲ τὰς μετὰ τῶν πολλῶν ὁμιλίας. τὰς γοῦν διατριβὰς καὶ αὐτὸς ἕωθεν μὲν ἐπὶ τῆς οἰκίας ἐποιεῖτο, ἁρμοζόμενος πρὸς λύραν τὴν ἑαυτοῦ φωνὴν καὶ ᾄδων παιᾶνας ἀρχαίους τινὰς τῶν Θάλητος. καὶ ἐπῇδε τῶν ῾Ομήρου καὶ ῾Ησιόδου ὅσα καθημεροῦν τὴν ψυχὴν ἐδόξαζε. καὶ ὀρχήσεις δέ τινας ὑπωρχεῖτο ὁπόσας εὐκινησίαν καὶ ὑγείαν τῷ σώματι παρασκευάζειν ᾤετο. τοὺς δὲ περιπάτους οὐδ’ αὐτὸς ἐπιφθόνως μετὰ πολλῶν ἐποιεῖτο, ἀλλὰ δεύτερος ἢ τρίτος ἐν ἱεροῖς ἢ ἄλσεσιν, ἐπιλεγόμενος τῶν χωρίων τὰ ἡσυχαίτατα καὶ περικαλλέστατα.

33. “He loved his friends overmuch and was the first to declare that friends possessions are common and that a friend is another self. When they were healthy, he always talked to them; when they were sick, he took care of their bodies. If they were mentally ill, he consoled them, as we said before, some with incantations and spells, others by music. He had songs and paeans for physical ailments: when he sang them, he relieved fatigue. He also could cause forgetfulness of grief, calming of anger, and redirection of desire.”

33.τοὺς δὲ φίλους ὑπερηγάπα, κοινὰ μὲν τὰ τῶν φίλων εἶναι πρῶτος ἀποφηνάμενος, τὸν δὲ φίλον ἄλλον ἑαυτόν. καὶ ὑγιαίνουσι μὲν αὐτοῖς ἀεὶ συνδιέτριβεν, κάμνοντας δὲ τὰ σώματα ἐθεράπευεν, καὶ τὰς ψυχὰς δὲ νοσοῦντας παρεμυθεῖτο, καθάπερ ἔφαμεν, τοὺς μὲν ἐπῳδαῖς καὶ μαγείαις τοὺς δὲ μουσικῇ. ἦν γὰρ αὐτῷ μέλη καὶ πρὸς νόσους σωμάτων παιώνια, ἃ ἐπᾴδων ἀνίστη τοὺς κάμνοντας. ἦν <δ’> ἃ καὶ λύπης λήθην εἰργάζετο καὶ ὀργὰς ἐπράυνε καὶ ἐπιθυμίας ἀτόπους ἐξῄρει.

Iamblichus, Life of Pythagoras 111–112

“Pythagoras believed that music produced great benefits for health, should someone apply it in the appropriate manner. For he was known to use this kind of cleansing and not carelessly. And he also called the healing from music that very thing, a purification. And he used a melody as follows during the spring season. He sat in the middle someone who could play the lyre and settled around him in a circle people who could sing. They would sing certain paeans as he played and through this they seemed to become happy, unified, and directed.

At another time they used music in the place of medicine, and there were certain songs composed against sufferings of the mind, especially despair and bitterness—songs which were created as the greatest aids. He also composed others against rage, desires, and every type of wandering of the soul. There was also another kind of performance he discovered for troubles: he also used dancing.

He used the lyre as an instrument since he considered flutes to induce arrogance as a dramatic sound which had no type of freeing resonance. He also used selected words from Homer and Hesiod for the correction of the soul.”
