PIRUSTAE(Πιροῦσται, Ptol. 2.17.8; Πειροῦσται, Strab. 7. p. 314), a people of Illyria, whom the Romans declared free of taxes, because they assisted the latter in subduing Gentius. (Liv. 45.26.) Strabo (l. c.) calls them a Pannonian people. Respecting the position of the Pirustae on the northern frontier of Dassaretia, see Vol. 1. 755b.
