This inscription recording an unequal alliance between the Spartans and the Erxadieis has been given dates ranging over almost the whole of the Peloponnesian League’s existence: recent arguments for a late date on the grounds of the formulations used are not cogent; the “exiles” mentioned are probably the Messenians settled at Naupactus between c. 455 and c. 400, and the lettering favours either c. 450 or c. 426.
