The Latin colony of Alba Fucens near the northwest corner of the lake was founded in the adjoining Aequian territory in 303, 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 (298 BC) farther west. The earliest pure Latin inscriptions of the district seem to be C.I.L. ix. 3827 and 3848 from the neighbourhood of Supinum; its character generally is of the Gracchan period, though it might be somewhat earlier.
