Passage 1.34.1
τὴν δὲ γῆν τὴν Ὠρωπίαν μεταξὺ τῆς Ἀττικῆς καὶ Ταναγρικῆς, Βοιωτίαν τὸ ἐξ ἀρχῆς οὖσαν, ἔχουσιν ἐφʼ ἡμῶν Ἀθηναῖοι, πολεμήσαντες μὲν τὸν πάντα ὑπὲρ αὐτῆς χρόνον, κτησάμενοι δὲ οὐ πρότερον βεβαίως πρὶν ἢ Φίλιππος Θήβας ἑλὼν ἔδωκέ σφισιν. ἡ μὲν οὖν πόλις ἐστὶν ἐπὶ θαλάσσης μέγα οὐδὲν ἐς συγγραφὴν παρεχομένη· ἀπέχει δὲ δώδεκα τῆς πόλεως σταδίους μάλιστα ἱερὸν τοῦ Ἀμφιαράου.
The Oropian territory that lies between Attica and Tanagra, originally belonging to Boeotia, is occupied in our time by the Athenians. They continually fought for it, but did not firmly obtain possession until Philip conquered Thebes and granted it to them. The city itself lies by the sea and offers nothing noteworthy for recording; but about twelve stades distant from the city is a sanctuary of Amphiaraus.
