C. Julius Caesar, Gallic War

When these answers were reported to Caesar, he sends embassadors to him a second time with this message. "Since, after having been treated with so much kindness by himself and the Roman people (as he had in his consulship been styled 'king and friend' by the senate [59 B.C.]), he makes this recompense to [Caesar] himself and the Roman people, [viz.] that when invited to a conference he demurs, and does not think that it concerns him to advise and inform himself about an object of mutual interest, these are the things which he requires of him; first, that he do not any more bring over any body of men across the Rhine into Gaul; in the next place, that he restore the hostages, which he has from the Aedui, and grant the Sequani permission to restore to them with his consent those hostages which they have, and that he neither provoke the Aedui by outrage nor make war upon them or their allies; if he would accordingly do this," [Caesar says] that "he himself and the Roman people will entertain a perpetual feeling of favor and friendship toward him; but that if he [Caesar] does not obtain [his desires] that he (forasmuch as in the consulship of Marcus Messala and Marcus Piso [61 B.C.] the senate had decreed that, whoever should have the administration of the province of Gaul should, as far as he could do so consistently with the interests of the republic, protect the Aedui and the other friends of the Roman people), will not overlook the wrongs of the Aedui."
