Gulf of Lion in the context of Embayment

The Rhône (/roʊn/ ROHN, French: [ʁon] ; Occitan: Ròse; Arpitan: Rôno) is a major river in France and Switzerland, rising in the Alps and flowing west and south through Lake Geneva and Southeastern France before discharging into the Mediterranean Sea (Gulf of Lion). At Arles, near its mouth, the river divides into the Great Rhône (French: le Grand Rhône; Occitan: Grand Ròse) and the Little Rhône (le Petit Rhône; Pichon Ròse). The resulting delta forms the Camargue region.

The river's source is the Rhône Glacier, at the eastern edge of the Swiss canton of Valais. The glacier is part of the Saint-Gotthard Massif, which gives rise to three other major rivers: the Reuss, Rhine and Ticino.

The mistral (French: [mistʁal]; Catalan: mestral; Corsican: maestrale; Croatian: maestral; Greek: μαΐστρος; Italian: maestrale; Maltese: majjistral) is a strong, cold, northwesterly wind that blows from southern France into the Gulf of Lion in the northern Mediterranean. It produces sustained winds averaging 50 km/h (30 mph), sometimes reaching 100 km/h (60 mph). It can last for several days. Periods of the wind exceeding 30 km/h (19 mph; 8.3 m/s; 16 kn) for more than sixty-five hours have been reported. It is most common in the winter and spring, and strongest in the transition between the two seasons.

It affects the northeast of the plain of Languedoc and Provence to the east of Toulon, where it is felt as a strong west wind. It has a major influence all along the Mediterranean coast of France, and often causes sudden storms in the Mediterranean between Corsica and the Balearic Islands.

Gallia Narbonensis (Latin for "Gaul of Narbonne", from its chief settlement) was a Roman province located in Occitania and Provence, in Southern France. It was also known as Provincia Nostra ("Our Province"), because it was the first Roman province north of the Alps, and as Gallia Transalpina ("Transalpine Gaul"), distinguishing it from Cisalpine Gaul in Northern Italy. It became a Roman province in the late 2nd century BC. Gallia Narbonensis was bordered by the Pyrenees Mountains on the west, the Cévennes to the north, the Alps on the east, and the Gulf of Lion on the south; the province included the majority of the Rhone catchment. The western region of Gallia Narbonensis was known as Septimania. The province was a valuable part of the Roman Empire, owing to the Greek colony and later Roman Civitas of Massalia, its location between the Spanish provinces and Rome, and its financial output.
