But, while by fixing such rules the pressure of those requisitions on the economy of the communities and of individuals in the province was doubtless mitigated here and there, it was by no means removed. In extraordinary crises this pressure unavoidably increased and often went beyond all bounds, for then in fact the requisitions not unfrequently assumed the form of a punishment imposed or that of voluntary contributions enforced, and compensation was thus wholly withheld.
Thus Sulla in 670-671 compelled the provincials of Asia Minor, who certainly had very gravely offended against Rome, to furnish to every common soldier quartered among them forty-fold pay (per day 16 -denarii- = 11 shillings), to every centurion seventy-five-fold pay, in addition to clothing and meals along with the right to invite guests at pleasure; thus the same Sulla soon afterwards imposed a general contribution on the client and subject communities,(12) in which case nothing, of course, was said of repayment.
