C. Caligula (40)

He levied new taxes, and such as were never before known, at first by the publicans, but afterwards, because their profit was enormous, by centurions and tribunes of the pretorian guards; no description of property or persons was exempted from some kind of tax or other. For all eatables brought into the city a certain excise was exacted; for all law-suits or trials, in whatever court, the fortieth part of the sum in dispute; and such as were convicted of compromising litigations were made liable to a penalty. Out of the daily wages of the porters he received an eighth, and from the gains of common prostitutes, what they received for one favour granted. There was a clause in the law, that all bawds who kept women for prostitution or sale, should be liable to pay, and that marriage itself should not be exempted.
