Anonymus 561 was the father of Euthymios 12; he was apparently a spatharios, later becoming patrikios and magistros, and subsequently was a monk of distinction who was still alive when Petros 126 wrote the Life of Ioannikios 2 (St. Ioannikios): Petrus, Vita Ioannicii 65 (Εὐθυμίῳ, τῷ υἱῷ τοῦ μαγίστρου, τοῦ πότε γεγονότος σπαθαρίου, νυνὶ δὲ ἐν τῇ μοναδικῇ τάξει κάλως διαπρέποντος), cf. Sabas, Vita Ioannicii 35 (Εὐθυμίου ἡγουμένου, υἱοῦ γενομένου πατρικίου τε καὶ μαγίστρου). His son was an hegoumenos probably late in the reign of Michael II (Michael 10) or soon afterwards, cf. Ioannikios 2, and therefore he must have been elderly when Petros 126 was writing. He may be identical with the patrikios and magistros Stephanos 128, who is mentioned by both Sabas 1 and Petros 126 shortly before the father of Euthymios 12. Grammatically the text of Petros 126 gives the above sense; but given the chronology it is perhaps possible that it was Euthymios 12 who was the spatharios and who flourished in the monastic life when Petros 126 was writing. The title of spatharios ranked much below that of magistros and there is no obvious reason why Petros 126 chose to record it in connection with this person.
