From Chapter 31 of the Decline & Fall

Almost all that is said of the bread, bacon, oil, wine, etc., may be found in the fourteenth book of the Theodosian Code, which expressly treats of the 'police' of the great cities. See particularly the titles iii. iv. xv. xvi. xvii. xxiv. The collateral testimonies are produced in Godefroy's Commentary, and it is needless to transcribe them. According to a law of Theodosius, which appreciates in money the military allowance, a piece of gold (eleven shillings) was equivalent to eighty pounds of bacon, or to eighty pounds of oil, or to twelve modii (or pecks) of salt (Cod. Theod. l. viii. tit. iv. leg. 17). This equation, compared with an-other seventy pounds of bacon for an amphora (Cod. Theod. l. xiv. tit. iv. leg. 4), fixes the price of wine at about sixteenpence the gallon.
