LEUCIEth. LEUCI (Λευκοί), a Gallic people (Strab. p. 193; Ptol. 2.9.13; Caes. Gal. 1. 40), between the Mediomatrici on the north and the Lingones on the south. They occupied the valley of the Upper Mosel. One of their chief towns was Tullum (Toul.) Their territory corresponded with the diocese of Toul, in which were comprised the dioceses of Nancy and Saint-Dié until 1774, when these two dioceses were detached from that of Toul. (Walekenaer, Géog. &c. vol. i. p. 531.) The Leuci are only mentioned once in Caesar, and with the Sequani and Lingones: they were to supply Caesar with corn. Pliny (4.17) gives the Leuci the title of Liberi. Lucan celebrates them in his poem (1.424) as skilled in throwing the spear:-- “Optimus excusso Leucus Rhemusque lacerto.
” Tacitus (Tac. Hist. 1.64) mentions “Leucorum civitas,” which is Tullum. [G.L]
