Born probably around 1110, Andronikos Kamateros was the son of
Gregory Kamateros, a man of humble origin but well educated, who held several senior government posts under emperors
Alexios I Komnenos and
John II Komnenos and advanced to the high rank of
sebastos, and of Irene Doukaina, probably a daughter of the
protostrator Michael Doukas, whose sister
Irene was wed to Alexios I. Andronikos had several siblings, but with the exception of a brother Michael, who died young, and possibly another brother named Theodore, on whose death
John Tzetzes composed an
epitaph, they are mostly unknown. The
sebastos and
logothetes tou dromou John Kamateros (logothetes tou dromou) was probably also his brother, rather than his son, as Polemis regards him. With Andronikos and John, the
Kamateros family reached the peak of its influence. His relationship to the ruling
Komnenian dynasty—from his mother's side, Andronikos was second cousin to Emperor
Manuel I Komnenos (r. 1143–80)—ensured his rise to prominence. Andronikos was awarded the high rank of
sebastos, and by the mid-1150s, Andronikos held the relatively senior post of
epi ton deeseon, in charge of petitions. He then advanced to the post of
eparchos of
Constantinople (1157–61) and finally to
megas droungarios tes viglas (1166–76), two of the highest judicial offices in the Empire. In 1161, he participated in an embassy that went to the
Principality of Antioch to escort Manuel I's second wife,
Maria of Antioch, to Constantinople. A skilled theologian, he played a prominent role in Manuel's dealings with the Church; not only did he edit Manuel's theological discussions as part of his
Sacred Arsenal (see
below), but in 1173 Manuel entrusted him with the enforcement of an imperial decree regarding absentee bishops, and elsewhere is seen introducing the abbot of the
Monastery of Patmos to Manuel. The time of his death is unknown, but was probably around 1180. Andronikos Kamateros was married and had several children, of whom
Basil also rose to high office. Of his two known daughters, Theodora married the
megas doux Michael Stryphnos, while
Euphrosyne married the future
Alexios III Angelos (r. 1195–1203). ==Writings==
