Oropus was originally a town of Boeotia; and, from its position in the maritime plain of the Asopus, it naturally belonged to that country.
[2] It was, however, a frequent subject of dispute between the Athenians and Boeotians; and the former people obtained possession of it long before the Peloponnesian War.
Strabo also describes Oropus as a Boeotian town;[9] but Livy,[10] Pausanias,[2] and Pliny the Elder[11] place it in Attica.
Pausanias expressly says that Oropus was upon the sea;[12] and the inhabitants had probably returned to their old town long before his time.
[15] According to Dicaearchus, the Oropians were notorious for their grasping exactions, levied upon all imports into their country,[8] and were for this reason satirised by Xenon, a comic poet: "All the tax collectors, all of them are abductors.
"[16] The modern village of Oropos stands at the distance of nearly two miles (3.2 km) from the sea, on the right bank of the Asopus: it contains some fragments of ancient buildings and sepulchral stones.
There are also Hellenic remains at Skála (Σκάλα) or wharf upon the bay, from which persons usually embark for Euboea: this place is also called ἐς τοὺς ἁγίους ἀποστόλους, from a ruined church dedicated to the Holy Apostles.
[2] Strabo places it in the district of Psophis, which stood between Rhamnus and Oropus, and which was subsequently an Attic deme.
Dicaearchus describes the road from Athens to Oropus as leading through bay-trees (διὰ δαφνίδων) and the temple of Amphiaraus.
