M. Tullius Cicero, On the Responses of the Haruspices
C. D. Yonge, Ed.

After that, when he saw you recovering your breath after your fear of bloodshed, when he saw your authority rising again above the waves of that slavery, and the recollection of, and regret for me, getting more vivid, then he began on a sudden to sell himself to you, though with the most treacherous design. Then he began to say, both here in this house and in the assemblies of the people, that the Sullan laws had been passed in opposition to the auspices; among which laws was that lex curiata on which the whole of his tribuneship depended, though he was too frantic to see that. He brought forward that most fearless man Marcus Bibulus. He asked him whether he had not always been observing the heavens when Caius Caesar was carrying those laws? He replied, that he always had been observing them at that time. He asked the augurs whether laws which had been passed under these circumstances had been duly passed? They said, such a proceeding was irregular. Some people, virtuous men, and men who had done great service to me, began to extol him; utterly ignorant I imagine, of the lengths to which his madness could carry him. He proceeded further. He began to inveigh against Cnaeus Pompeius, the originator, as he was accustomed to boast, of all his designs. He gained great popularity in the people's eyes.
