Alight, open carriage with two wheels, like a gig, adapted for two persons. Its form is
sculptured on the monumental column at Igel, near Treves (see illustration). It had a box or
case, probably under the seat. The cisia
were quickly drawn by mules
). Cicero mentions the case of a messenger who travelled
fifty-six miles in ten hours in such vehicles, which
were kept for hire at the stations along the great roads—a proof that the
ancients considered six Roman miles per hour as an extraordinary speed. The conductors of
these hired gigs were called cisiarii
, and were subject to penalties for
careless or dangerous driving See Cic. Pro Rosc. Amerin.
