ANGĂRĪA (ἀγγαρεία, Hdt. ἀγγαρήϊον), a word borrowed from the
Persians, signifying a system of posting by relays of horses, which
was used among that people, and which, according to Xenophon, was
established by Cyrus. The term was adopted by the Romans under the
empire to signify compulsory service in forwarding the messages of
the state. The Roman _angaria_, also called _angariarum exhibitio_
or _praestatio_, included the maintenance and supply, not only of
horses, but of ships and messengers, in forwarding both letters and
burdens; it is defined as a _personale munus_; and there was no
ground of exemption from it allowed, except by the favour of the
emperor.
ANGĬPORTUS, or ANGĬPORTUM, a narrow lane between two rows of houses,
which might either be what the French call a _cul-de-sac_, or it
might terminate at both ends in some public street.
