Now it so happens that there _were_ important events which occurred in the Roman empire, and connected with its decline and fall, of sufficient importance to be noticed in a series of calamitous events, which corresponded with the symbol here, as above explained. They were such as these: (a) The _general_ severity of taxation, or the oppressive burdens laid on the people by the emperors. In the account which Mr. Gibbon gives of the operation of the _Indictions_, and _Superindictions_, though the specific laws on this subject pertained to a subsequent period, the general nature of the taxation of the empire and its oppressive character may be seen (_Decline and Fall_, i. 357‒359). A general estimate of the amount of revenue to be exacted was made out, and the collecting of this was committed to the pretorian prefects, and to a great number of subordinate officers. “The lands were measured by surveyors who were sent into the provinces; their nature, whether arable, or pasture, or woods, was distinctly reported; and an estimate made of their common value, from the average produce of five years. The number of slaves and of cattle constituted an essential part of the report; an oath was administered to the proprietors, which bound them to disclose the true state of their affairs; and their attempts to prevaricate or elude the intention of the legislature were severely watched, and punished as a capital crime, which included the double guilt of treason and of sacrilege. According to the different nature of lands, their real produce in the various articles of _wine or oil, corn or barley_, wood or iron, was transported by the labour or at the expense of the provincials to the imperial magazines, from whence they were occasionally distributed for the use of the court or of the army, and of the two capitals, Rome and Constantinople,” i. p. 358. Comp. Lactant. _de Mort. Persecut._, c. 23. (b) The particular order, under this oppressive system of taxation, respecting the preservation of vineyards and oliveyards, may be referred to, also, as corresponding to the command sent forth under this rider, not to “hurt the oil and the wine.” That order was in the following words:――“If any one shall sacrilegiously cut a vine, or stint the fruit of prolific boughs, and craftily feign poverty in order to avoid a fair assessment, he shall, immediately on detection, suffer death, and his property be confiscated” (_Cod. Theod._ l. xiii. lib. xi. seq.; Gibbon, i. 358, note). Mr. Gibbon remarks: “Although this law is not without its studied obscurity, it is, however, clear enough to prove the minuteness of the inquisition, and the disproportion of the penalty.” (c) Under this general subject of the severity of taxation――as a fact far-spreading and oppressive, and as so important as to hasten the downfall of the empire, may be noticed a distinct edict of Caracalla as occurring more directly in the period in which the rider with
