Closing of the Latin Confederation
In manifest connection with this crisis in the relations between Rome and Latium stands the closing of the Latin confederation,(14) which took place about the year 370, although we cannot precisely determine whether it was the effect or, as is more probable, the cause of the revolt of Latium against Rome which we have just described.
14. In the list given by Dionysius (v. 61) of the thirty Latin federal cities--the only list which we possess--there are named the Ardeates, Aricini, Bovillani, Bubentani (site unknown), Corni (rather Corani), Carventani (site unknown), Circeienses, Coriolani, Corbintes, Cabani (perhaps the Cabenses on the Alban Mount, Bull, dell' Inst. 1861, p. 205), Fortinei (unknown), Gabini, Laurentes, Lanuvini, Lavinates, Labicani, Nomentani, Norbani, Praenestini, Pedani, Querquetulani (site unknown), Satricani, Scaptini, Setini, Tiburtini, Tusculani, Tellenii (site unknown), Tolerini (site unknown), and Veliterni.
The occasional notices of communities entitled to participate, such as of Ardea (Liv. xxxii. x), Laurentum (Liv. xxxvii. 3), Lanuvium (Liv. xli. 16), Bovillae, Gabii, Labici (Cicero, pro Plane. 9, 23) agree with this list. Dionysius gives it on occasion of the declaration of war by Latium against Rome in 256, and it was natural therefore to regard--as Niebuhr did--this list as derived from the well-known renewal of the league in 261, But, as in this list drawn up according to the Latin alphabet the letter -g appears in a position which it certainly had not at the time of the Twelve Tables and scarcely came to occupy before the fifth century (see my Unteritalische Dial. p. 33), it must be taken from a much more recent source; and it is by far the simplest hypothesis to recognize it as a list of those places which were afterwards regarded as the ordinary members of the Latin confederacy, and which Dionysius in accordance with his systematizing custom specifies as its original component elements.
As was to be expected, the list presents not a single non-Latin community; it simply enumerates places originally Latin or occupied by Latin colonies--no one will lay stress on Corbio and Corioli as exceptions. Now if we compare with this list that of the Latin colonies, there had been founded down to 372 Suessa Pometia, Velitrae, Norba, Signia, Ardea, Circeii (361), Satricum (369), Sutrium (371), Nepete (371), Setia (372). Of the last three founded at nearly the same time the two Etruscan ones may very well date somewhat later than Setia, since in fact the foundation of every town claimed a certain amount of time, and our list cannot be free from minor inaccuracies.
If we assume this, then the list contains all the colonies sent out up to the year 372, including the two soon afterwards deleted from the list, Satricum destroyed in 377 and Velitrae divested of Latin rights in 416; there are wanting only Suessa Pometia, beyond doubt as having been destroyed before 372, and Signia, probably because in the text of Dionysius, who mentions only twenty-nine names, --SIGNINON-- has dropped out after --SEITINON--. In entire harmony with this view there are absent from this list all the Latin colonies founded after 372 as well as all places, which like Ostia, Antemnae, Alba, were incorporated with the Roman community before the year 370, whereas those incorporated subsequently, such as Tusculum, Lanuvium, Velitrae, are retained in it.
As regards the list given by Pliny of thirty-two townships extinct in his time which had formerly participated in the Alban festival, after deduction of seven that also occur in Dionysius (for the Cusuetani of Pliny appear to be the Carventani of Dionysius), there remain twenty-five townships, most of them quite unknown, doubtless made up partly of those seventeen non-voting communities--most of which perhaps were just the oldest subsequently disqualified members of the Alban festal league--partly of a number of other decayed or ejected members of the league, to which latter class above all the ancient presiding township of Alba, also named by Pliny, belonged.
