History of the Peloponnesian War

The foundation of this town, evidently meant to annoy Euboea (the passage across to Cenaeum in that island being a short one), at first caused some alarm at Athens, which the event however did nothing to justify, the town never giving them any trouble.

The reason of this was as follows. The Thessalians, who were sovereign in those parts, and whose territory was menaced by its foundation, were afraid that it might prove a very powerful neighbor, and accordingly continually harassed and made war upon the new settlers, until they at last wore them out in spite of their originally considerable numbers, people flocking from all quarters to a place founded by the Lacedaemonians, and thus thought secure of prosperity. On the other hand the Lacedaemonians themselves, in the persons of their governors, did their full share towards ruining its prosperity and reducing its population, as they frightened away the greater part of the inhabitants by governing harshly and in some cases not fairly, and thus made it easier for their neighbors to prevail against them.
