Andronikos Doukas is the son of caesar John Doukas, cousin of Michael VII and father of Eirene, the wife of Alexios I Komnenos. He was appointed domestikos of the Schols of the Orient in ca. 1072 and died as the monk Antonios on 14 October 1077. He is mentioned with all three of the titles that appear on our seals in a Patmos document by which he received in 1073 an imperial donation. See Polemis, Doukai, 55-59; cf. Zacos-Veglery, 1473 and Patmos, II, no. 50. See also BZS 1958.106.2491.
