Hey manitas - I had to go and look up Casalpine Gauls (I just love learning something new every day); and here's what I found at en.wikipedia.org:

Cisalpine Gaul (Latin: Gallia Cisalpina, meaning "Gaul this side of the Alps") was a province of the Roman Republic, in Emilia and Lombardy of modern-day northern Italy. Sometimes referred to as Provincia Ariminum. Gallia Transpadana denoted that part of Cisalpine Gaul between the Po and the Alps. The province was governed from Mutina (modern-day Modena), where in 73 BCE the forces under Spartacus defeated the legion of Cassius Longinus, the provincial governor.

The province was merged into Italia about 43–42 BCE, as part of Octavian's 'Italicisation' program during the Second Triumvirate. Previously, its border had been marked by the small river called the Rubicon.

The end of the provincia required a new governing law, though its contemporary name is unknown. The parts of it that are inscribed on a bronze tablet preserved in the museum at Parma are entirely concerned with arranging the judiciary establishment appointed two viri and four viri juri dicundo a Prefect of Mutina is also mentioned in the lex [1].

Virgil was born in Gallia Cisalpina, the province's most famous son.

Transalpine Gaul was a Roman province whose name was chosen to distinguish it from Cisalpine Gaul. Transalpine means "that side of the Alps", while Cisalpine would mean "this side of the Alps". Cisalpine Gaul was on the east of the Alps range, while Transalpine Gaul was to the west. Together, the regions made up the region of Gaul, which was called Gallia by the Romans. The region that Transalpine Gaul contained is now most of France. Cisalpine Gaul included areas in France and Northern Italy.

The Latin name for this province was Gallia Transalpina. It became a Roman province in 121 BC. Later it was renamed Gallia Narbonensis, after its capital the Roman colony of Narbo Martius (Narbonne), which was founded on the coast in 118 BC.

All the best, Áine
