The Autariatæ were the most populous and the bravest tribe of the Illyrians. Formerly, there were continual disputes between them and the Ardiæi respecting the salt which was spontaneously formed on the confines of their respective territories, in the spring season, from water which flows through a valley. The salt concreted five days after the water was drawn and deposited in reservoirs. The right of collecting salt was, by agreement, to be exercised alternately by each party, but the compact was broken and war was the consequence. After the Autariatæ had subdued the Triballi, a people whose territory extended a journey of fifteen days, from the Agrianæ to the Danube, they became masters of the Thracians and Illyrians. The Autariatæ were first conquered by the Scordisci, and afterwards by the Romans, who overpowered the Scordisci, for a long time a powerful nation.
