 to order more corn than the tithe of wheat amounted to, they were bound by capitulation to pay for the surplus at the rate of four sestertii, or eightpence sterling the peck; and this had probably been reckoned the moderate and reasonable, that is, the ordinary or average contract price of those times; it is equal to about one-and-twenty shillings the quarter. Eight-and-twenty shillings the quarter was, before the late years of scarcity, the ordinary contract price of English wheat, which in quality is inferior to the Sicilian, and generally sells for a lower price in the European market. The value of silver, therefore, in those ancient times, must have been to its value in the present, as three to four inversely; that is, three ounces of silver would then have purchased the same quantity of labor and commodities which four ounces will do at present. When we read in Pliny, therefore, that Seius bought a white nightingale, as a present for the empress Agrippina, at the price of six thousand sestertii, equal to about fifty pounds of our present money; and that Asinius Celer purchased a surmullet at the price of eight thousand sestertii, equal to about sixty-six pounds thirteen shillings and fourpence of our present money; the extravagance of those prices, how much soever it may surprise us, is apt, notwithstanding, to appear to us about one-third less than it really was. Their real price, the quantity of labor and subsistence which was given away for them, was about one-third more than their nominal price is apt to express to us in the present times. Seius gave for the nightingale the command of a quantity of labor and subsistence equal to what £66 13s. 4d. would purchase in the present times; and Asinius Celer gave for a surmullet 1
