Silver stood to copper in Egypt as 80 to 1 (Brugsch), or 120 to 1 (Revillout); in early Italy and Sicily as 250 to 1 (Mommsen), or 120 to 1 (Soutzo), under the empire 120 to 1, and under Justinian 100 to 1.
The other ratio of Revillout and Hultsch, 320 hons = cubit cubed, is certainly approximate.
The wholesale theory of Revillout (35) that all Hebrew and Syrian measures were doubled by the Ptolemaic revision, while retaining the same names, rests entirely on the resemblance of the names apet and epha, and of log to the Coptic and late measure lok.
The "argenteus" (as Revillout transcribes a sign in the papyri) (35) was of 5 shekels, or 1090; it arose about 440 B.C., and became after 160 B.C. a weight unit for copper.
Revillout, in Rev. eg.
Revillout addressed himself with success to the task of interpreting the legal documents of demotic which had been almost entirely neglected for thirty years.
