Anonymus 54 was supposedly a Jewish sorcerer (Ἑβραίων τινι μάγῳ), visited by Photios 1 (the future patriarch) in pursuit of knowledge; Anonymus 54 promised to teach Photios 1 all pagan knowledge and make him the most learned of all men; in return for a denial of Christ, Anonymus 54 is supposed to have given Photios 1 access to the secret books of sorcery of the Jews: Ps.-Symeon 670. The story is doubtless fiction and the sorcerer fictitious. The whole account in Pseudo-Symeon is very hostile to Photios 1.
