Angarīa
(
ἀγγαρεία). A word borrowed from the Persians, signifying
a system of posting which was used among that people, and which, according to Xenophon, was
established by Cyrus. Horses were provided at certain distances along the principal roads of
the empire; so that couriers (
ἄγγαροι), who also of course
relieved one another at certain distances, could proceed without interruption both night and
day (
Herod.viii. 98; iii. 126;
Xen.
Cyrop. viii. 6.17). Among the Romans, the word was used to denote
compulsory service in forwarding imperial messages. See
Digest, l. tit. 4, s.
18.4, 29; and the article
Cursus Publicus.
