Constantine IX Monomachos
In the 11th century, the most important holder of the office was Nicholas, who was "parakoimōmenos" and "proedros" as well as Domestic of the Schools under Constantine VIII () and served again in the same offices for a time under Constantine IX Monomachos (). John Komnenos, a relative of the Emperor John II Komnenos (), was named as "parakoimōmenos" and entrusted with the charge of state affairs along with Gregory Taronites. In the late 12th century, the eunuch Nikephoros under Andronikos I Komnenos () and the likewise eunuch John Oinopolites under Alexios III Angelos () are the only known holders.
