History of Old Rome by Theodor Mommsen.
by Paolo Giuseppe Mazzarello
Let's begin from its origins.
The mortgages did not exist.
The wife had her husband and did not belong to the State.
The creditor was owner of something.
The debitor became owner of that same thing only when had paid his creditor.
This way the distrains did not exist as well as the procurers.
A foreigner could become guest of a Roman citizen.
All the Roman inhabitants wore the same pattern of tunic.
The travertine blocks got the sun on the dry calctufe.
The peperino stones were less precious but very useful.
