Note 4 — Chapter II · Slavery Defined. PROPERTY IN A HUMAN BEING.
Reading edition
Prof. B. B. Edwards says—“From the time of Augustus to Justinian we may allow three slaves to one free man; we shall thus have a free population in Italy of 6,944,000; and of slaves 20,832,000.”
On the treatment of Roman slaves Guizot remarks that “it would be easy to give the most frightful and heartrending accounts of the manner in which the ancient Romans treated their slaves. Entire volumes are occupied with the details.” (Hist. Civilization.)
