Such was the nature and such the influence of the Roman religion in its pure, unhampered, and thoroughly national development. Its national character was not infringed by the fact that, from the earliest times, modes and systems of worship were introduced from abroad; no more than the bestowal of the rights of citizenship on individual foreigners denationalized the Roman state. An exchange of gods as well as of goods with the Latins in older time must have been a matter of course; the transplantation to Rome of gods and worships belonging to less cognate races is more remarkable. Of the distinctive Sabine worship maintained by the Tities we have already spoken.(14) Whether any conceptions of the gods were borrowed from Etruria is more doubtful: for the Lases, the older designation of the genii (from -lascivus-), and Minerva the goddess of memory (-mens-, -menervare-), which it is customary to describe as originally Etruscan, were on the contrary, judging from philological grounds, indigenous to Latium. It is at any rate certain, and in keeping with all that we otherwise know of Roman intercourse that the Greek worship received earlier and more extensive attention in Rome than any other of foreign origin. The Greek oracles furnished the earliest occasion of its introduction. The language of the Roman gods was on the whole confined to Yea and Nay or at the most to the making their will known by the method of casting lots, which appears in its origin Italian;(15) while from very ancient times--although not apparently until the impulse was received from the East--the more talkative gods of the Greeks imparted actual utterances of prophecy. The Romans made efforts, even at an early period, to treasure up such counsels, and copies of the leaves of the soothsaying priestess of Apollo, the Cumaean Sibyl, were accordingly a highly valued gift on the part of their Greek guest-friends from Campania. For the reading and interpretation of the fortune-telling book a special college, inferior in rank only to the augurs and Pontifices, was instituted in early times, consisting of two men of lore (-duoviri sacris faciundis-), who were furnished at the expense of the state with two slaves acquainted with the Greek language. To these custodiers of oracles the people resorted in cases of doubt, when an act of worship was needed in order to avoid some impending evil and they did not know to which of the gods or with what rites it was to be performed. But Romans in search of advice early betook themselves also to the Delphic Apollo himself. Besides the legends relating to such an intercourse already mentioned,(16) it is attested partly by the reception of the word -thesaurus- so closely connected with the Delphic oracle into all the Italian languages with which we are acquainted, and partly by the oldest Roman form of the name of Apollo, -Aperta-, the "opener," an etymologizing alteration of the Doric Apellon, the antiquity of
