Anonymus 763 was the brother of Ignatius the Deacon (Ignatios 9); he had a copy of the four Gospels made at his own expense and at his death bequeathed it to Ignatios (Βίβλος πάλαι πεπόνηται ἐκ τῶν οικείων πόρων τῷ ἐμῷ γνησίῳ ὁμαίμονι τῆς ἁγιαστικῆς τετρακτύος τῶν Εὐαγγελιστῶν, ἥν μοι καὶ πρὸς τὰ ἐκεῖ μεταθέμενος, οἷα δή τινα κλῆρον, εἴασεν): Ignatius Diac., Ep. 54. The letter was addressed to the patriarch Methodios, and was therefore written between 843 and 847. The book came into Ignatios 9's possession some time before 826; his brother must therefore have died before that date.
