Ius Anŭli Aurei
The right to wear a gold ring was originally a military distinction (
Verr.
iii. 80, 187), and was ultimately the prerogative of the knights (
equites) of the military tribune (
App. Pun.
104), and also of such senators as were
nobiles or had served as
legati. The right was also granted as a special privilege to individuals
by the military commanders and provincial governors, and carried with it all the dignities of
knighthood. Thus Sulla gave the
anulus aureus to the actor Roscius
(Macrob.
Sat. ii. 10). Under the Empire, the emperor bestowed the
ius anuli at will. See Lange,
Röm. Alterth. ii. 8, 163;

Privatleben, 680 foll., and Herbert Spencer's
Ceremonial
Institutions, ch. ix.
