Julius Caesar,
"De Bello Gallico" and Other Commentaries
“ As they could not of themselves prevail on them, they send ambassadors to Dumnorix the Aeduan, that through his intercession they might obtain their request from the Sequani. Dumnorix, by his popularity and liberality, had great influence among the Sequani, and was friendly to the Helvetii, because out of that state he had married the daughter of Orgetorix; and, incited by lust of sovereignty, was anxious for a revolution, and wished to have as many states as possible attached to him by his kindness towards them. ”
