Ἀχαΐα

[sc. Another name for] Hellas. For Memmius¹ the consul set out against the Corinthians and deprived Metellus of the victory that was in his grasp. He attacked the hard-pressed Achaeans near the Isthmus, defeated them, and without a blow he took Corinth. This city was first of the whole Hellenic world at this time. This seems to be the reason why even now they call Hellas "Achaia".² The Romans came and changed the name of the whole territory³ to [that of] the subdued people, who were at that point the leaders of Hellas.
Also [sc. attested is the phrase] "Achaian missile," in reference to those who throw with good aim. In light of the fact that this sort of missile is most suitable of all against a siege, the missile of the slingers from Achaia.
