The Romans, probably, as an equally southern people, had
the same original temperament: but the stern character of their
national discipline, like that of the Spartans, made them an
example of the opposite type of national character; the greater
strength of their natural feelings being chiefly apparent in the
intensity which the same original temperament made it possible to
give to the artificial.

temperament

Question:

What factors contributed to the differences in national character between Romans and other southern people, despite their similar original temperaments?

Answer (optional):

Some factors that contributed to the differences in national character between Romans and other southern people, despite their similar original temperaments, include the stern character of their national discipline, the intensity of their natural feelings, and the influence of their original temperament on their artificial character. These factors allowed the Romans to develop a more unyielding and focused character, setting them apart from other excitable southern people like the Greeks and the Irish Celts.
