ion, and then
to take sides with one party or the other, it mattered little with
which, for the affair almost always resulted, in the end, in his making
himself master of both. The manner, however, in which this sort of
operation was performed, can best be illustrated by an example, and we
will take for the purpose the case of Ariovistus.

[Sidenote: Ariovistus.]
[Sidenote: The Aeduans.]

Ariovistus was a German king. He had been nominally a sort of ally of
the Romans. He had extended his conquests across the Rhine into Gaul,
and he held some nations there as his tributaries. Among these, the
Aeduans were a prominent party, and, to simplify the account, we will
take their name as the representative of all who were concerned. When
Caesar came into the region of the Aeduans, he entered into some
negotiations with them, in which they, as he alleges, asked his
assistance to enable them to throw off the dominion of their German
enemy. It is probable, in fact, that there was some proposition of this
kind from them, for Caesar had abundant means of inducing them to make
it, if he was disposed, and the receiving of such a communication
furnished the most obvious and plausible pretext to authorize and
justify his interposition.

Caesar accordingly sent a messenger across the Rhine to Ariovistus,
saying that he wished to have an interview with him on business of
importance, and asking him to name a time which would be convenient to
him for the interview, and also to appoint some place in Gaul where he
would attend.

To this Ariovistus replied, that if he had, himself, any business with
Caesar, he would have waited upon him to propose it; and, in the same
manner, if Caesar wished to see him, he must come into his own
dominions. He said that it would not be safe for him to come into Gaul
without an army, and that it was not convenient for him to raise and
equip an army for such a purpose at that time.

[Sidenote: His message.]

Caesar sent again to Ariovistus to say, that since he was so unmindful
of his obligations to the Roman people as to refuse an interview with
him on business of common interest, he would state the particulars that
he required of him. The Aeduans, he said, were now his allies, and under
his protection; and Ariovistus must send back the hostages which he held
from them, and bind himself henceforth not to send any more troops
across the Rhine, nor mak
