AEQUI, an ancient people of Italy, whose name occurs
constantly in Livy's first decade as hostile to Rome in the
first three Centuries of the city's existence. They occupied
the upper reaches of the valleys of the Anio, Tolenus and
Himella; the last two being mountain streams runing northward
to join the Nar. Their chief centre is said to have been
taken by the Romans about 484 B.C. (Diodorus xi. 40) and
again about ninety years later (id. xiv. 106), but they
were not finally subdued Until the end of the second Samnite
war (Livy ix. 45,; x. 1; Diod. xx. 101), when they seem to
have received a limited form of franchise (Cic. Off. i.
II, 35). All we know of their subsequent political condition
is that after the Social war the folk of Cliternia and Nersae
appear united in a res Publica Aequiculorum, which was a
municipium of the ordinary type (C.I.L. ix. p. 388). The
Latin colonies of Alba Fucens (304 B.C.) and Carsioll (298
B.C.) must have spread the use of Latin (or what passed as
such) all over the district; through it by the chief (and for
some time the only) route (Pia Valeria) to Luceria and the
south. Of the language spoken by the Aequi before the Roman
conquest we have no record; but since the Marsi (q.v.), who
lived farther east, spoke in the 3rd century B.C. a dialect
closely akin to Latin, and since the Hernici (q.v.), their
neighbours to the south-west, did the same, we have no ground
for separating any of these tribes from the Latian group
(see LATINI). If we could be certain of the origin of the
a in their name and of the relation between its shorter
and its longer form (note that the i in Aequicidus is
long--Virgil, Aen. vii. 74----which seems to connect it
with the locative of aequum ``a plain,'' so that it would
mean ``dwellers in the plain''; but in the historical period
they certainly lived mainly in the hills), we should know
whether they were to be grouped with the q or the p
dialects, that is to say, with Latin on the one hand, which
preserved an original q, or with the dialect of Velitrae,
commonly called Volscian (and the Volsci were the constant
allies of the Aequi), on the other hand, in which, as in the
Iguvine and Samnite dialects, an original q is changed into
p. There is no decisive evidence to show whether the q
in Latin aequus represents an Indo-European q as in Latin
quis, Umbro-Volsc. pis, or an Indo-European k+u as in
equus, Umb. ekvo-. The derivative adjective Aequicus
might be taken to range them with the Volsci rather than the
Sabini, but it is not clear that this adjective was ever used
as a real ethnicon; the name of the tribe is always Aeqai,
or Aequicoli. At the end of the Republican period the Aequi
appear, under the name Aequiculi or Aequicoh, organized as a
municipium, the territory of which seems to have comprised
the upper part of the valley of the Salto, still known as
Cicolano. It is probable, however, that they continued to
live in their villages as before. Of these Nersae (mod.
Nesce) was the most considerable. The polygonal terrace
walls, which exist in considerable numbers in the district,
are shortly described in Romische Mitteilungen (1903), 147
seq., but require further study. See further the articles
MARSI, VOLSCI, LATINI, and the references there given; the
place-names and other scanty records of the dialect are collected
