Joannes41. Of CONSTANTINOPLE, 4. or Joannes VI. in the list of patriarchs of that city. He was appointed patriarch by the Emperor Philippicus Bardanes, A. D. 712, on account of his agreement with that emperor in his monothelite opinions, and in rejecting the authority of the sixth oecumenical (third Constantinopolitan) council. Cyrus, the predecessor of Joannes, was deposed to make way for him. According to Gave, Joannes was deposed not long after his elevation, in consequence apparently of the deposition of his patron Philippicus, and the elevation of Artemius or Anastasius II. Theophanes does not notice the fate of Joannes, but records the elevation of his successor Germanus, metropolitan of Cyzicus, to the patriarchate of Constantinople, A. D. 715.
