Histories

They order the eldest of that family not to enter their town-hall (which the Achaeans call the People's House)[*](From lew/s or lho/s.) and themselves keep watch there. If he should enter, he may not come out, save only to be sacrificed. They say as well that many of those who were to be sacrificed had fled in fear to another country, and that if they returned at a later day and were taken, they were brought into the town-hall. The guides showed Xerxes how the man is sacrificed, namely with fillets covering him all over and a procession to lead him forth.

It is the descendants of Phrixus' son Cytissorus who are treated in this way, because when the Achaeans by an oracle's bidding made Athamas son of Aeolus a scapegoat for their country and were about to sacrifice him, this Cytissorus came from Aea in +Caucasus (region (general)), Asia Colchis and delivered him, thereby bringing the god's wrath on his own descendants.
