Marsian language
The Marsian language is the extinct language of the Marsi. It is classified by the Linguist List as one of the Umbrian group of languages.
Phonology
Their language differs very slightly from Roman Latin of that date; for apparently contracted forms, such as Fougno instead of Fucino, may really only be a matter of spelling. In final syllables, the diphthongs ai, ei, and oi all appear as e. On the other hand, the older form of the name of the tribe shows its derivation and exhibits the assibilation of -tio- into -tso-, proper to the Oscan language but strange to classical Latin.Corpus
The Marsian inscriptions are dated by the style of the alphabet from about 300 to 150 BC. Conway lists nine inscriptions, one from Ortona [dei Marsi|Ortona] and two each from Marruvium, Lecce, Trasacco and Luco. In addition, there are a few glosses, a few place names and a few dozen personal names in Latin form.Bronze of Lake Fucinus
The Bronze of Lake Fucinus was an inscribed bronze plaque found in 1877 near Luco during the draining of the lake, from an ancient settlement that had been covered by the lake. The bronze was placed in the Museum of Prince Alessandro Torlonia, where it was photographed for publication. It was lost in 1894 and it has not been seen since. The text of the plaque is as follows:It seems to be or describe a votive offering perhaps of boars to the local goddess Anctia on behalf of the Marsian Legions.
