Regia
(
τὸ βασίλειον, ῥηγία). Originally the building in which
the king (
rex), as the head of the State religion, performed the usual
rites; and later, the one set apart for the Pontifex Maximus and perhaps for the Rex Sacrorum.
(See
Pontifex;
Rex Sacrorum.) The word is also the pure Latin equivalent of
basilica. See
Basilica.
