Ἀκάκιος

The patriarch of Constantinople, he was revered as no other. For he was the guardian of orphans, and it was evident to all that he managed the affairs of the orphans well and with pleasure. Moreoever, he became an acquaintance of the emperor Leo with whom he found immense favor. He [Leo] confided his affairs, both public and private, to this man first of all. When he assembled the senate, he invited this man as well and turned the beginning of every discussion over to him.
This Akakios realized the savagery of Leo Makelles¹ toward those who had offended him in some way and had accurately divined his character; but because this was something only those who flattered him had the opportunity to observe, he made a habit of marvelling at all that he did. Nevertheless he was readily able to rein [Leo] in and easily made him slacken his anger. He also brought about the salvation of many who ran afoul of him, and managed to have those sentenced to life-long exile recalled to their homeland.
After the death of Gennadios, patriarch of Constantinople, he was nominated to serve in that priesthood with the backing of Zenon. Since he was a natural leader and took all the churches under his direct control, he exercised a deliberate discrimination concerning those who were appointed to the churches. They in gratitude dedicated images of him in their prayer chambers. Thus, when images of him appeared in all the churches, some people began to think that he, in a pursuit of empty glory, had ordered their dedication, and no small confirmation of this suspicion was supplied by the mosaic image fashioned in the church by the harbor. For although the entire work had been completed in the time of Gennadios, in a conspicuous place in the temple they portrayed [Akakios] and after him the Savior saying to Gennadios 'destroy this temple', and over him 'after you I will raise him up.'² As a result of such images, then, Akakios, though he was generous and a capable leader, nevertheless seemed to all to be excessively ambitious.³
