Latium (Lazio in Italian) is a region of central Italy, bordered by Tuscany, Umbria, Abruzzo, Marche, Molise, Campania and the Tyrrhenian Sea. It comprises 5 provinces: Rome, Viterbo, Latina, Frosinone, and Rieti. The regional capital is Rome; the current President of the Region is Piero Marrazzo (center-left, elected 2005). The name of the region also survives in the tribal designation of the ancient population of Latins, from whom the Romans originated. In Roman mythology, the shadowy king Latinus allegedly gave his name to the region. Modern linguists postulate origins in a Proto-Indo-European language (PIE) root *stela- (to spread, extend), expressing the idea of "flat land" (in contrast to the local Sabine high country). But the name may originate from an earlier, non Indo-European one. See the Online Etymological Dictionary. Since Latium is respected more as a designation for ancient Rome, it is not used as a label on maps or globes.
