ANDRONICO, CAMATERO. – A descendant of the Ducas family and a relative of the emperor Manuel Comnenus, who around 1150 appointed him commander of his guard and governor of Constantinople. He took part on several occasions in the religious assemblies convened by the emperor, in which, although a simple layman, he revealed a profound theological knowledge.
Between 1170 and 1175 he composed the Sacred Arsenal (Ἰεξὰ ὀνδωθῆκη), a still unpublished treatise, in the form of a dialogue, on the procession of the Holy Spirit, directed against the Latins and the Armenians. Giovanni Bekkos, patriarch of Constantinople, refuted him, employing the same arguments put forward by A.
