As the period, during which the husbandman guided his plough on the seven hills of Rome just as on the other hills of Latium, and the usually unoccupied places of refuge on particular summits alone presented the germs of a more permanent settlement, corresponds to the earliest epoch of the Latin stock without trace of traffic or achievement; as thereafter the flourishing settlement on the Palatine and in the "Seven Rings" was coincident with the occupation of the mouths of the Tiber by the Roman community, and with the progress of the Latins to a more stirring and freer intercourse, to an urban civilization in Rome more especially, and perhaps also to a more consolidated political union in the individual states as well as in the confederacy; so the Servian wall, which was the foundation of a single great city, was connected with the epoch at which the city of Rome was able to contend for, and at length to achieve, the sovereignty of the Latin league.

A similar change of sound is exhibited in the case of the following formations, all of them of a very ancient kind: -pars--portio-, -Mars- -Mors-, -farreum- ancient form for -horreum-, -Fabii- -Fovii-, -Valerius- -Volesus-, -vacuus- -vacivus-.

The -- synoikismos-- did not necessarily involve an actual settlement together at one spot; but while each resided as formerly on his own land, there was thenceforth only one council-hall and court-house for the whole (Thucyd.ii.

15; Herodot.i.

170).
