Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
The intention of the legislator,
when instead of mortgaging he prescribed the immediate transfer of
the property to the creditor with a view to prevent insolvency and to
devolve the burdens of the state on the real holders of the soil,(3)
was evaded by the rigorous system of personal credit, which might
be very suitable for merchants, but ruined the farmers.
The free
divisibility of the soil always involved the risk of an insolvent
agricultural proletariate; and under such circumstances, when all
burdens were increasing and all means of deliverance were foreclosed,
distress and despair could not but spread with fearful rapidity among
the agricultural middle class.
