Tarasios was born and raised in the city of
Constantinople. A son of a high-ranking judge, Tarasios was related to important families, including that of the later Patriarch
Photios I of Constantinople. He had an elder brother, Sisinnios, who was captured during the
invasion of Calabria in 788–789. Tarasios had embarked on a career in the secular administration and had attained the rank of
senator, eventually becoming imperial secretary (
asekretis) to the Emperor
Constantine VI and his mother, the Empress
Irene of Athens. Since Tarasios exhibited both
Iconodule sympathies and the willingness to follow imperial commands when they were not contrary to the faith, he was selected as Ecumenical Patriarch of Constantinople by Empress Irene in 784, even though he was a
layman at the time. Nevertheless, like all
educated Byzantines, he was well versed in
theology, and the election of qualified laymen as bishops was not unheard of in the history of the Church. and a council be called to address the iconoclast controversy. == Second Council of Nicaea ==
