Bishop of Constantinople from 360 to 370

Imperial Roman prince and consul (366-369)

Saint Triphyllius (; also spelled Tryphillius, Triphylius) was born in Constantinople in the early fourth century. He was educated in law at the school of Beirut. He converted to Christianity and was named bishop of Nicosia. Triphyllius was a follower of Saint Spyridon of Trimythous. He was also an ardent supporter of Saint Athanasius of Alexandria against the Arians, and he was consequently persecuted by them. Saint Jerome considered him one of the most eloquent Church figures of the era. ==References==

Cylaces or Glak (, misspelled in the manuscripts of Faustus of Byzantium's history) was a 4th-century Armenian eunuch who occupied the office of '''' (grand chamberlain). He initially defected to the Sasanian side during Shapur II's invasion of Armenia, but later rejoined the Armenians in 368 and fought Shapur II's forces. In 370, he sent messengers to Shapur II, promising him to betray the Armenian king Pap (). However, this ploy was discovered by Pap, who had Cylaces assassinated.
