Andronikos Doukas was born circa 1057, the third son of Constantine X Doukas and Eudokia Makrembolitissa.[1] He studied under Michael Psellos, and several works survive that were compiled by the prominent scholars of the day to aid him in his studies: one treatise on geometry by Psellos and two philosophical essays by John Italos.
