Titus Livius (Livy), The History of Rome, Book 2
Rev. Canon Roberts, Ed.

[2] There were some young men of high birth in Rome who during the late reign had done pretty much what they pleased, and being born companions of the young Tarquins were accustomed to live in royal fashion. [3] Now that all were equal before the law, they missed their former licence and complained that the liberty which others enjoyed had become slavery for them; as long as there was a king, there was a person from whom they could get what they wanted, whether lawful or not, there was room for personal influence and kindness, he could show severity or indulgence, could discriminate between his friends and his enemies. [4] But the law was a thing, deaf and inexorable, more favourable to the weak than to the powerful, showing no indulgence or forgiveness to those who transgressed; human nature being what it was, it was a dangerous plan to trust solely to one's innocence. [5] When they had worked themselves into a state of disaffection, envoys from the royal family arrived, bringing a demand for the restoration of their property without any allusion to their possible return. An audience was granted them by the senate, and the matter was discussed for some days; fears were expressed that the non-surrender would be taken as a pretext for war, while if surrendered it might provide the means of war. [6] The envoys, meantime, were engaged on another task: whilst ostensibly seeking only the surrender of the property they were secretly hatching schemes for regaining the crown. [7] Whilst canvassing the young nobility in favour of their apparent object, they sounded them as to their other proposals, and meeting with a favourable reception, they brought letters addressed to them by the Tarquins and discussed plans for admitting them secretly at night into the City.
