Blasios 1 was a chartophylax; Blasios 1 was one of the friends of the patriarch Ignatios 1; after the first overthrow of Ignatios 1 (in 858) he was one of those persecuted for supporting him and, probably around August 859, he was punished for his outspokenness by having his tongue cut out: Nicetas, Vita Ignatii 513C (ὅτε δὴ καὶ τὸν χαρτοφύλακα Βλάσιον διὰ τὴν ὑπὲρ τῆς ἀληθείας παρρησίαν ἐγλωσσοτόμησαν). The punishment of Ignatios 1's supporters is associated with the patriarch's exile to Mitylene, in August 859. Photius (Photios 1) wrote a letter to the kaisar Bardas 5 in August 859 interceding on his behalf; Blasios 1 had suffered beatings and imprisonment and had now had his tongue cut out, and Photios 1 observed that if all his attempts to help people were so successful he may as well give up: Photius, Ep. 6 (I 58ff. Laourdas-Westerink) (to Bardas 5 περὶ κληρικοῦ τοῦ Βλασίου κινδυνεύσαντος).
