The Marsi were an Italic people of ancient Italy, whose chief centre was Marruvium, on the eastern shore of Lake Fucinus (which was drained in the time of Claudius).
[3] After a short-lived revolt two years later, for which they were punished by the loss of territory,[4] they were readmitted to the Roman alliance and remained faithful down to the Social War, their contingent[5] being always regarded as the flower of the Italian forces.
[6] The Latin colony of Alba Fucens near the northwest corner of the lake was founded in the adjoining Aequian territory in 303 BC so that, from the beginning of the 3rd century, the Marsians were in touch with a Latin-speaking community, to say nothing of the Latin colony of Carsioli farther west.
All the coins of Pompaedius Silo have the Latin legend "Italia", while the other leaders in all but one case used Oscan.
Angitia was widely worshipped in the central highlands[8] as a goddess of healing, especially skilled to cure serpent bites by charms and the herbs of the Marsian woods, which was carried out by local inhabitants until modern times.
