M. Tullius Cicero Pro P. Sulla 12

[12] Who, then, was present at your counsels? All these men whom you see here, giving Sulla the countenance of their presence; and among the first was Quintus Hortensius—who, by reason of his honour and worth, and his admirable disposition towards the republic, and because of his exceeding intimacy with and excessive attachment to your father, was greatly moved by the thoughts of the common danger, and most especially by the personal peril of your father. Therefore, he was defended from the charge of being implicated in that conspiracy by that man who was present at and acquainted with all your deliberations, who was a partner in all your thoughts and in all your fears; and, elegant and argumentative as his speech in repelling this accusation was, it carried with it as much authority as it displayed of ability. Of that conspiracy, therefore, which is said to have been formed against you, to have been reported to you, and to have been revealed by you, I was unable to say anything as a witness. For I not only found out nothing, but scarcely did any report or suspicion of that matter reach my ears.
