“Once a woman declared that she was desperately in love with him, and he took her to bed with him. "How shall I enter that item in your expense ledger?" asked his accountant later, on learning that she had got 4,000 gold pieces out of him; and Vespasian replied, "Just put it down to 'passion for Vespasian'."”
Expugnatus autem a quadam, quasi amore suo deperiret, cum perductae pro concubitu sestertia quadringenta donasset, admonente dispensatore, quem ad modum summam rationibus vellet inferri, "Vespasiano," inquit, "adamato".
