remembered that among the Romans it was soldiers who served as police,
whether at Rome or in the provinces. The Imperial Guards, consisting
of 12,000 troops, were stationed just outside the gates, in order to
secure the safety and position of the emperor himself, if any attempt
should be made against his person or authority. The rich and important
town of Lugdunum (or Lyons) had a small garrison of 1200 men, and a
certain number of troops were always to be found in garrison in those
great towns where factious disturbances were either probable or
possible. Thus at Alexandria, where the Jews were fanatical and at
loggerheads with the Greeks, and where the native Egyptians were no
less fanatical and might be at loggerheads with both, it was necessary
to keep a disciplinary force in readiness. Somewhat similar was the
case at Antioch, where the discords of the Greeks, Syrians, and Jews
stood in need of the firm Roman hand. Nor could a similar regiment be
spared from Jerusalem. The western towns were generally smaller in
size, more homogeneous, and more tranquil. It was around the Levant
that the popular _émeute_ was most to be feared. Doubtless one may
meet, whether in the New Testament or in Roman and Greek writers, with
frequent mention of soldiers, and we make acquaintance with an
occasional centurion--something socially above a colour-sergeant and
below a captain--or other officer in various parts of the empire. But
it should be understood that, except in such places as those which
have been named, soldiers were distributed in small handfuls, to act
as _gendarmerie_, to deal with brigands, to serve as bodyguard and
orderlies to a governor, to bear despatches, to be custodians of state
prisoners. To these classes belong the centurions of the _Acts of the
Apostles_, while Lysias was the colonel of the regiment keeping order
in Jerusalem.
