syncelli

In the Latin Church they never became very influential, though popes and bishops had syncelli as witnesses of their mode of life

The Catholic Encyclopedia, Volume 14: Simony-Tournon 1840-1916 1913

In the course of time the patriarchs took two or more syncelli, the most distinguished of whom was called protosyncellus (protosygkellos).

Henceforth their functions were equivalent to those of the "permanent synod" and the syncelli at Constantinople

The Catholic Encyclopedia, Volume 3: Brownson-Clairvaux 1840-1916 1913

Given the position of the pope and his intimate relations both to the individual cardinals and to such a close corporation as the college itself, at papal functions, in papal elections, in synods, in the consistory, in the conduct of diplomatic negotiations, it is easy to understand how all cardinals, including cardinal-priests and cardinal-deacons came to outrank bishops and archbishops, and after the fourteenth century even patriarchs, just as at Constantinople the syncelli eventually outranked bishops and archbishops.
