Strabo, Geography

Next in order, at a distance of two hundred stadia, comes Sybaris, founded by the Achaeans; it is between two rivers, the Crathis and the Sybaris. Its founder was Is of Helice.¹ In early times this city was so superior in its good fortune that it ruled over four tribes in the neighborhood, had twenty- five subject cities, made the campaign against the Crotoniates with three hundred thousand men, and its inhabitants on the Crathis alone completely filled up a circuit of fifty stadia. However, by reason of luxury² and insolence they were deprived of all their felicity by the Crotoniates within seventy days; for on taking the city these conducted the river over it and submerged it. Later on, the survivors, only a few, came together and were making it their home again, but in time these too were destroyed by Athenians and other Greeks, who, although they came there to live with them, conceived such a contempt for them that they not only slew them but removed the city to another place near by and named it Thurii, after a spring of that name. Now the Sybaris River makes the horses that drink from it timid, and therefore all herds are kept away from it; whereas the Crathis makes the hair of persons who bathe in it yellow or white, and besides it cures many afflictions. Now after the Thurii had prospered for a long time, they were enslaved by the Leucani, and when they were taken away from the Leucani by the Tarantini, they took refuge in Rome, and the Romans sent colonists to supplement them, since their population was reduced, and changed the name of the city to Copiae.
