elements found in the language. Geographical distribution Inscriptions have been found Cabeço das Fráguas (in Guarda), in Moledo (Viseu), in Arroyo de la Luz (in Cáceres) and most recently in Ribeira da Venda. Taking into account Lusitanian theonyms, anthroponyms and toponyms, the Lusitanian sphere would include modern northern Portugal and adjacent areas in southern Galicia, with the centre in Serra da Estrela. The most famous inscriptions are those from Cabeço das Fráguas and Lamas de Moledo in Portugal and Arroyo de la Luz in Spain. Ribeira da Venda is the most recently discovered (2008). A bilingual Lusitanian–Latin votive inscription is reported to attest the ancient name of Portuguese city of Viseu: Vissaîegobor. Writing system All the known inscriptions are written in the Latin alphabet, which was borrowed by bilingual Lusitanians, who were literate in Latin, to write Lusitanian since Lusitanian had no writing system of its own. It is difficult to determine if the letters have a different pronunciation than the Latin values but the frequent alternations of c with g (porcom vs. porgom) and t with d (ifadem vs. ifate), and the frequent loss of g between vowels, points to a lenis pronunciation compared to Latin. In particular, between vowels and after r, b may have represented the sound , and correspondingly g was written for , and d for . Inscriptions Lamas de Moledo:Hübner, E. (ed.)
