   • 44 BCE – 43 BCE, Cicero, Philippicae V.6.7:

     Hoc ne Cotyla quidem dicere auderet. Quid enim in eum non cadit, qui, cuius acta se defendere dicit, eius eas leges pervertit, quas maxime laudare poteramus? Ille paludes siccare voluit, hic omnem Italiam moderato homini, L. Antonio, dividendam dedit. Quid? hanc legem populus Romanus accepit, quid? per auspicia ferri potuit? Silet augur verecundus sine collegis de auspiciis. Quamquam illa auspicia non egent interpretatione; Iove enim tonante cum populo agi non esse fas quis ignorat? Tribuni plebi tulerunt de provinciis contra acta C. Caesaris, ille biennium, hi sexennium. Etiam hanc legem populus Romanus accepit? quid? promulgata fuit, quid? non ante lata quam scripta est, quid? non ante factum vidimus, quam futurum quisquam est suspicatus?
