Ioseph 5 was a hegoumenos (ἡγούμενος); he was supposedly a victim of persecution at the hands of the patriarch Photios 1 and with a fellow hegoumenos and sufferer Euthymios 2 visited the hesychast and monk Ioannes 94 in his cave, who comforted and strengthened them: Ps.-Symeon 672. The story is one of several in a narrative which is very hostile to Photios 1. For a doubt about the truth of the tale, see Euthymios 2.
