ἐξ Ἀκραιφνίου δὲ ἰόντι εὐθεῖαν ἐπὶ λίμνην τὴν Κηφισίδα—οἱ δὲ Κωπαΐδα ὀνομάζουσι τὴν αὐτήν— πεδίον καλούμενόν ἐστιν Ἀθαμάντιον· οἰκῆσαι δὲ Ἀθάμαντα ἐν αὐτῷ φασιν. ἐς δὲ τὴν λίμνην ὅ τε ποταμὸς ὁ Κηφισὸς ἐκδίδωσιν ἀρχόμενος ἐκ Λιλαίας τῆς Φωκέων καὶ διαπλεύσαντί εἰσι Κῶπαι. κεῖνται δὲ αἱ Κῶπαι πόλισμα ἐπὶ τῇ λίμνῃ, τούτου δὲ καὶ Ὅμηρος ἐποιήσατο ἐν καταλόγῳ μνήμην· ἐνταῦθα Δήμητρος καὶ Διονύσου καὶ Σαράπιδός ἐστιν ἱερά.
λέγουσι δὲ οἱ Βοιωτοὶ καὶ πολίσματα ἄλλα πρὸς τῇ λίμνῃ ποτὲ Ἀθήνας καὶ Ἐλευσῖνα οἰκεῖσθαι, καὶ ὡς ὥρᾳ χειμῶνος ἐπικλύσασα ἠφάνισεν αὐτὰ ἡ λίμνη. οἱ μὲν δὴ ἰχθῦς οἱ ἐν τῇ Κηφισίδι οὐδέν τι διάφορον ἐς ἄλλους ἰχθῦς τοὺς λιμναίους ἔχουσιν· αἱ δὲ ἐγχέλεις αὐτόθι καὶ μεγέθει μέγισται καὶ ἐσθίειν εἰσὶν ἥδισται.
Κωπῶν δὲ ἐν ἀριστερᾷ σταδίους προελθόντι ὡς δώδεκα εἰσὶν Ὄλμωνες, Ὀλμωνέων δὲ ἑπτά που στάδια Ὕηττος ἀφέστηκε κῶμαι νῦν τε οὖσαι καὶ εὐθὺς ἐξ ἀρχῆς· μοίρας δὲ ἐμοὶ δοκεῖν τῆς Ὀρχομενίας εἰσὶ καὶ αὗται καὶ πεδίον τὸ Ἀθαμάντιον. καὶ ὅσα μὲν ἐς Ὕηττον ἄνδρα Ἀργεῖον καὶ Ὄλμον τὸν Σισύφου λεγόμενα ἤκουον, προσέσται καὶ αὐτὰ τῇ Ὀρχομενίᾳ συγγραφῇ· θέας δὲ ἄξιον ἐν μὲν Ὄλμωσιν οὐδʼ ἐπὶ βραχύτατον παρεῖχον οὐδέν, ἐν Ὑήττῳ δὲ ναός ἐστιν Ἡρακλέους καὶ ἰάματα εὕρασθαι παρὰ τούτου τοῖς κάμνουσιν ἔστιν, ὄντος οὐχὶ ἀγάλματος σὺν τέχνῃ, λίθου δὲ ἀργοῦ κατὰ τὸ ἀρχαῖον.
Ὑήττου δὲ στάδια ὡς εἴκοσιν ἀπέχουσι Κύρτωνες· τὸ δὲ ἀρχαῖον ὄνομα τῷ πολίσματί φασιν εἶναι Κυρτώνην. ᾤκισται δὲ ἐπὶ ὄρους ὑψηλοῦ, καὶ Ἀπόλλωνός ἐστιν ἐνταῦθα ναός τε καὶ ἄλσος· ἀγάλματα δὲ ὀρθὰ Ἀπόλλωνος καὶ Ἀρτέμιδός ἐστιν. ἔστι δὲ αὐτόθι καὶ ὕδωρ ψυχρὸν ἐκ πέτρας ἀνερχόμενον· νυμφῶν δὲ ἱερὸν ἐπὶ τῇ πηγῇ καὶ ἄλσος οὐ μέγα ἐστίν, ἥμερα δὲ ὁμοίως πάντα ἐν τῷ ἄλσει δένδρα.
ἐκ δὲ Κυρτώνων ὑπερβάλλοντι τὸ ὄρος πόλισμά ἐστι Κορσεία, ὑπὸ δὲ αὐτῷ δένδρων ἄλσος οὐχ ἡμέρων· πρῖνοι τὸ πολύ εἰσιν. Ἑρμοῦ δὲ ἄγαλμα οὐ μέγα ἐν ὑπαίθρῳ τοῦ ἄλσους ἕστηκε. τοῦτο ἀπέχει Κορσείας ὅσον τε ἥμισυ σταδίου. καταβάντων δὲ ἐς τὸ χθαμαλὸν ποταμὸς Πλατάνιος καλούμενος ἐκδίδωσιν ἐς θάλασσαν· ἐν δεξιᾷ δὲ τοῦ ποταμοῦ Βοιωτῶν ἔσχατοι ταύτῃ πόλισμα οἰκοῦσιν Ἁλὰς ἐπὶ θαλάσσῃ, ἣ τὴν Λοκρίδα ἤπειρον ἀπὸ τῆς Εὐβοίας διείργει.
Following the straight road from Acraephnium to the Cephisian or, as it is sometimes called, the Copaic Lake, we come to the Athamantian plain: they say that Athamas dwelt in it. The river Cephisus falls into the lake: it rises at Lilaea in Phocis. And sailing across the lake you come to Copae, a town on the bank of the lake.
This town is mentioned by Homer in the Catalogue. Here are sanctuaries of Demeter, Dionysus, and Serapis. The Boeotians say that there were once other towns named Athens and Eleusis beside the lake, but that in winter the lake flooded and destroyed them. The fish in the Cephisian Lake do not differ from the fish usually found in lakes; but the eels in it are very large and very good to eat.
About twelve furlongs to the left of Copae is Olmones, and about seven furlongs from Olmones is Hyettus: both places are and have always been mere villages. Both they and the Athamantian plain belong, I think, to the district of Orchomenus. The traditions which I heard about Hyettus an Argive, and Olmus, son of Sisyphus, will be included in my account of Orchomenus. At Olmones they had nothing whatever to show that was worth seeing; but at Hyettus there is a temple of Hercules, and the sick can be healed by him: he is represented, not by an artificial image, but in the ancient fashion by an unwrought stone.
About twenty furlongs distant from Hyettus is Cyrtones: the old name of the town, they say, was Cyrtone. It stands on a lofty mountain, and there is a temple and grove of Apollo here: there are images of Apollo and Artemis, both represented standing. Here, too, there is cold water welling up from a rock. There is a sanctuary of the nymphs at the spring and a small grove. All the trees in the grove have been planted.
In crossing the mountain from Cyrtones you come to a town Corsea: beneath it is a grove of forest trees, most of them evergreen oaks. In the grove stands a small image of Hermes in the open air: it is about half a furlong from Corsea. Having descended into the level ground we reach a river called the Platanius, flowing into the sea. On the right of the river is Halae, the last town in Boeotia. It is situated on the arm of the sea which separates the mainland of Locris from Euboea.
