sound changes, and influences in conjugation and word order. The Vulgar Latin in the region of Gallia took on a distinctly local character, some of which is attested in graffiti, which evolved into the Gallo-Romance dialects which include French and its closest relatives. The influence of substrate languages may be seen in graffiti showing sound changes that matched changes that had occurred earlier in the indigenous languages, especially Gaulish. The Vulgar Latin in the North of Gaul evolved into the langues d'oïl and Franco-Provencal, and the dialects in the South evolved into the modern Occitan and Catalan tongues. Other languages held to be "Gallo-Romance" include the Gallo-Italic languages and the Rhaeto-Romance languages. Latin epigraphy in Gaul has peculiarities such as the occasional variant instead of . Gallo-Roman art Roman culture introduced a new phase of anthropomorphized sculpture to the Gaulish community, synthesized with Celtic traditions of refined metalworking, a rich body of urbane Gallo-Roman silver developed, which the upheavals of the 3rd and the 5th centuries motivated hiding away in hoards, which have protected some pieces of Gallo-Roman silver, from villas and temple sites, from the universal destruction of precious metalwork in circulation. The exhibition of Gallo-Roman silver highlighted specifically Gallo-Roman silver from the treasures found at Chaourse (Aisne), Mâcon (Saône et Loire), Graincourt-lès-Havrincourt (Pas de Calais), Notre-Dame d'Allençon (Maine-et-Loire) and Rethel (Ardennes, found in 1980). Gallo-Roman sites The two most Romanized of the three Gauls were bound together in a network of Roman roads, which linked cities. Via Domitia (laid out in 118 BC), reached from Nîmes to the Pyrenees, where it joined the Via Augusta at the Col de Panissars. Via Aquitania reached from Narbonne, where it connected to the Via Domitia, to the Atlantic Ocean through Toulouse to Bordeaux. Via Scarponensis connected Trier to Lyon through Metz. Sites, restorations, museums At Périgueux, France, a luxurious Roman villa called the Domus of Vesunna, built round a garden courtyard surrounded by a colonnaded peristyle enriched with bold tectonic frescoing, has been handsomely protected in a modern glass-and-steel structure that is a fine example of archaeological museum-making (see external link). Lyon, the capital of Roman Gaul, is now the site of the Gallo-Roman Museum of Lyon (rue Céberg), associated with the remains of the theater and odeon of Roman Lugdunum. Visitors are offered a clear picture of the daily life, economic conditions, institutions, beliefs, monuments and artistic achievements of the
