The rocky path becomes wider and has stone reinforcements on the downhill side, which shows that it was once used by large herds. This draille led from Saint-Jean-du-Gard to the summer pastures on Mont Aigoual. At the Col de Mercou pass (570 m), there are panoramic views northwards over the Corniche des Cevennes. The pass was once a site for trade and commerce, with its own market. Its name is derived from Mercury, the god of travellers and commerce. There are also references to Melkart, a Phoenician deity: Semitic traders left traces of their passage here in the architecture of the old proto-historic bridges. Melkart or Melqart was the tutelary god of the city of Tyre - whose name means “strong king” in Phoenician – and was the god of riches, industry and navigation. He was worshipped in the tenth century BC.
