A league seems therefore to have been determined on.

We have not indeed any positive evidence of its existence till the close of the war; but the probabilities are wholly in favor of its having taken effect from the first.

We may conclude therefore that the princes of Asia Minor, having either met in conclave or communicated by embassies, resolved to make common cause, if the Medes crossed the Halys; and that, having already acted under Lydia in the expulsion of the Cimmerians from their territories, they naturally placed her at their head when they coalesced for the second time.
