27. In the meantime, so soon as the disaster at Thermopylai had come about, the Thessalians sent a herald forthwith to the Phokians, against whom they had a grudge always, but especially because of the latest disaster which they had suffered: for when both the Thessalians themselves and their allies had invaded the Phokian land not many years before this expedition of the king, they had been defeated by the Phokians and handled by them roughly. For the Phokians had been shut up in Mount Parnassos having with them a soothsayer, Tellias the Eleian; and this Tellias contrived for them a device of the following kind:—he took six hundred men, the best of the Phokians, and whitened them over with chalk, both themselves and their armour, and then he attacked the Thessalians by night, telling the Phokians beforehand to slay every man whom they should see not coloured over with white. So not only the sentinels of the Thessalians, who saw these first, were terrified by them, supposing it to be something portentous and other than it was, but also after the sentinels the main body of their army; so that the Phokians remained in possession of four thousand bodies of slain men and shields; of which last they dedicated half at Abai and half at Delphi; and from the tithe of booty got by this battle were made the large statues which are contending for the tripod in front of the temple 19 at Delphi, and others similar to these are dedicated as an offering at Abai. 28. Thus had the Phokians done to the Thessalian footmen, when they were besieged by them; and they had done irreparable hurt to their cavalry also, when this had invaded their land: for in the pass which is by Hyampolis they had dug a great trench and laid down in it empty wine-jars; and then having carried earth and laid it on the top and made it like the rest of the ground, they waited for the Thessalians to invade their land. These supposing that they would make short work with the Phokians, 20 riding in full course fell upon the wine-jars; and there the legs of their horses were utterly crippled. 29. Bearing then a grudge for both of these things, the Thessalians sent a herald and addressed them thus: "Phokians, we advise you to be more disposed now to change your minds and to admit that ye are not on a level with us: for in former times among the Hellenes, so long as it pleased us to be on that side, we always had the preference over you, and now we have such great power with the Barbarian that it rests with us to cause you to be deprived of your land and to be sold into slavery also. We however, though we have all the power in our hands, do not bear malice, but let there be paid to us fifty talents of silver in return for this, and we will engage to avert the dangers which threaten to come upon your land."
