which means a person placed over, was
given as a title in the later times of the Roman Empire to many officers: of
these the most important was the Praepositus Sacri
originally a freedman (cf. Suet.
16), but afterwards of high rank as chief chamberlain
in the emperor's palace (Cod. 12, tit. 5; Cod. Theod. 6, tit. 8). Under him
was the Primicerius, together with the Cubicularii and the corps of
Silentiarii, commanded by three decuriones, who preserved silence in the
interior of the palace. (Cod. 12, tit. 16; Friedländer, S.
1.54; Walter, Gesch. des röm. Rechts,
§ 340, 2nd ed.)
