Velleius Paterculus, Historiae Romanae  2.60.3  (ca. A.D. 30):


Hunc protinus Antonius consul superbe excepit (neque is erat contemptus, sed metus) vixque admisso in Pompeianos hortos loquendi secum tempus dedit, mox etiam velut insidiis eius petitus sceleste insimulare coepit, in quo turpiter deprehensa eius vanitas est.

On his arrival, Antonius, the consul, received him haughtily—out of fear, however, rather than contempt—and grudgingly gave him, after he had secured admission to Pompeius' gardens, a few moments conversations with himself; and it was not long before Antonius began wickedly to insinuate that an attempt had been made upon his life through plots fostered by Octavius.  (F.
