53. 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.
