This statue was dedicated by Achaeans who had fought alongside the Attalid army at the battle of Magnesia. The Achaean League had made an alliance with king Eumenes in 191 B.C.; see P.Thonemann, "The Attalid State, 188-133 BC", page 33 ( academia.edu ).
This statue of Attalos son of king Attalos was dedicated to Athena Nikephoros, on account of his virtue and courage, and his goodwill towards them, by the Achaeans who crossed over the sea in accordance with their alliance with his brother, king Eumenes, to participate in the war against Antiochos, and they joined in fighting the battle in Lydia by the river Phrygios.
