The Celto-Ligurian Oppidum
Between the 4h and 2nd centuries B.C., the Salyens, the largest of the Celto-Ligurian tribes in Provence, built a rampart of stones on the peaks that surrounded the valley of Notre_Dame-de-Laval, and constructed an oppidum, or town, around the spring in the valley, which was known for its healing powers. A shrine was built at the spring to Glanis, a Celtic god. The town grew, and a second wall was built in the 2nd century.
The town had a strong Celtic identity, shown by the names of the residents (Vrittakos, Eporix, Litumaros) by the names of the local gods (Glanis and his companions, the Glanicae, (similar to the Roman Matres); and the goddesses Rosmerta and Epona); by the statues and pottery; by the customs, such as displaying the severed heads of enemies at the city gate; and by the cooking utensils found in the ruins, which showed that the people of Glanis boiled their food in pots, rather than frying it in pans like other Mediterranean tribes.
The people of Glanum were in early contact with the Greek colony of Marseille, which had been founded in about 600 B.C. The contact influenced the architecture and art of Glanum- villas were built in the Hellenic style. But by the 2nd century there conflicts and wars between the Salyens and the Greeks of Marseille. The Greeks of Marseille, not having a powerful army, called upon the assistance of their Roman allies. In 125 B.C. the Salyens were defeated by the army of the Roman consul Marcus Fulvius Flaccus, and the following year decisively defeated by C. Sextus Calvinus. Many of the old monuments of Glanum were destroyed,
Despite the defeat, the town prospered again, thanks to the attraction of the healing spring. The city produced its own silver coins and built new monuments. The prosperity lasted until 90 B.C. when the Salyens again rebelled against Rome. The rebellion was crushed again, this time by the Consul Caecilius, and the public buildings of Glanum were again destroyed. dismantled, and replaced by more modest structures. I
