During the same summer war broke out between the Epidaurians and Argives. The alleged ground for this was that the Epidaurians were not sending the sacrifice to Apollo Pythaeus, which it was incumbent on them to render in payment for pasturage, and the Argives exercised chief authority over the sanctuary;[*](Probably the temple of Apollo Pythaeus referred to is that which alone of all the buildings in Asine the Argives spared when they destroyed that town; cf. Paus. II. xxxvi. 5.) but even apart from this motive Alcibiades and the Argives deemed it advisable, if they could, to bring Epidaurus into the Argive alliance, both for the sake of keeping Corinth quiet, and because they thought the Athenians would be able to bring aid to Argos by a shorter way, from Aegina as base, than by sailing round Scyllaeum.[*](A promontory between Hermione and Troezene. The short route was from Aegina to the neighbouring coast of Epidaurus and thence to Argos; if Epidaurus was hostile or neutral, reinforcements had to be carried round Scyllaeum to the Gulf of Nauplia and thence by land to Argos.) The Argives, then, were preparing, as of their own motion, to invade Epidaurus for the exaction of the offering.
