Hippocrates of Cos, Critical Days 302
“And whenever the liver swells more against his lungs, someone goes mad. He thinks he sees before his eyes creeping things and all kinds of beasts, fighting soldiers even as he believes that he is fighting with them. He speaks as if he is seeing these things and lashes out and threatens if someone forbids him from going out. If he stands, he may not be able to raise his legs and falls. His feet are always cold and whenever he sleeps, he jumps up from slumber and has witnessed frightening dreams.
We know that this fitfulness and fearing comes from dreams: whenever he calms down, he describes the kinds of dreams that he shaped out with his body and was describing with his tongue. He suffers these things in this way. And there are times when he is speechless for a whole day and night, gasping deeply for breath. When he stops this mad episode, he is immediately sensible again and if someone asks him a question, he responds right away and understands everything which was said. But, then later again, he falls under the same symptoms. This malady strikes most often when someone is abroad, especially if someone is walking on a deserted road. But it does happen other times too.’
καὶ ὁκόταν τὸ ἧπαρ μᾶλλον ἀναπτυχθῇ πρὸς τὰς φρένας, παραφρονέει· καὶ προφαίνεσθαί οἱ δοκέει πρὸ τῶν ὀφθαλμῶν ἑρπετὰ καὶ ἄλλα παντοδαπὰ θηρία, καὶ ὁπλίτας μαχομένους, καὶ αὐτὸς αὐτοῖς δοκέει μάχεσθαι· καὶ τοιαῦτα λέγει ὡς ὁρέων, καὶ ἐξέρχεται, καὶ ἀπειλεῖ, ἢν μή τις αὐτὸν ἐῴη διεξιέναι· καὶ ἢν ἀναστῇ, οὐ δύναται αἴρειν τὰ σκέλεα, ἀλλὰ πίπτει. οἱ δὲ πόδες αἰεὶ ψυχροί γίνονται· καὶ ὁκόταν καθεύδῃ, ἀναΐσσει ἐκ τοῦ ὕπνου, καὶ ἐνύπνια ὁρῇ φοβερά. τῷδε δὲ γινώσκομεν ὅτι ἀπὸ ἐνυπνίων ἀναΐσσει καὶ φοβέεται· ὅταν ἔννοος γένηται, ἀφηγεῖται τὰ ἐνύπνια τοιαῦτα ὁκοῖα καὶ τῷ σώματι ἐποίεέ τε καὶ τῇ γλώσσῃ ἔλεγε. ταῦτα μὲν οὖν ὧδε πάσχει. ἔστι δ᾿ ὅτε καὶ ἄφωνος γίνεται ὅλην τὴν ἡμέρην καὶ τὴν νύκτα, ἀναπνέων πολὺ ἀθρόον πνεῦμα. ὅταν δὲ παύσηται παραφρονέων, εὐθὺς ἔννοος γίνεται, καὶ ἢν ἐρωτᾷ τις αὐτόν, ὀρθῶς ἀποκρίνεται, καὶ γινώσκει πάντα τὰ λεγόμενα· εἶτ᾿ αὖθις ὀλίγῳ ὕστερον ἐν τοῖσιν αὐτοῖσιν ἄλγεσι κεῖται. αὕτη ἡ νοῦσος προσπίπτει μάλιστα ἐν ἀποδημίῃ, καὶ ἤν πῃ ἐρήμην ὁδὸν βαδίσῃ· λαμβάνει δὲ καὶ ἄλλως.
