Personification of quiet, the religious worship of which is documented exclusively by the mention of a sanctuary of Q. (fanum Quietis) on the via Labicana (Liv. 4,41,8). The inscription Quies Augustorum can be found on coins of Diocletianus and Maximianus after their abdication in AD 305; however, it must be seen in connection with the relief they felt at their withdrawal from official duties, rather than as in fact reflecting religious practice.
