Hippocrates of Cos, Epidemics 48
“A young man who had run on a rough road developed pain in his heel, especially close to the bottom. The area did not permit any draining of liquid because it was still producing moisture. On the fourth day, after his run, the whole area started turning dark right up to the joint of the ankle and below to the arch of the foot. It did not break out completely, instead he died first. He lived twenty full days after his run.”
Νεηνίσκος ὁδὸν τρηχείην τροχάσας ἤλγει τὴν πτέρνην, μάλιστα τὸ κάτω μέρος, ἀπόστασιν δὲ ὁ τόπος οὐκ ἐλάμβανεν οὐδεμίαν ὡς ξυνάγων ὑγρόν. ἀλλὰ τεταρταίῳ τε ἐόντι αὐτῷ ἐμελαίνετο πᾶς ὁ τόπος ἄχρι τοῦ ἀστραγάλου καλεομένου καὶ τοῦ κοίλου τοῦ κατὰ τὸ στῆθος τοῦ ποδός, καὶ τὸ μελανθὲν οὐ περιερράγη, ἀλλὰ πρότερον ἐτελεύτα· τὰς πάσας δὲ ἐβίου ἡμέρας εἴκοσιν ἀπὸ τοῦ δρόμου.
