Antonios 1 was a patrikios and domestikos of the Scholai (πατρικίου καὶ δομεστίκου τῶν σχολῶν) under Constantine V (Konstantinos 7); Antonios 1 shared the emperor's iconoclast views and took part with Konstantinos 7 in the persecution of iconophiles in Constantinople; the date was late in Constantine V (Konstantinos 7)'s reign, after 767: Theoph. AM 6259. See also Petros 8. In 782 Antonios 1 was still domestikos (τὸν δομέστικον), i.e. of the Scholai, under Constantine VI (Konstantinos 8) and Eirene 1, having presumably continued in office throughout the reign of Leo IV (Leo 4); when the caliph Harun al-Rashid (Harun 1) invaded Roman territory and reached Chrysopolis, Antonios 1 was sent by Eirene 1 with the tagmata; he occupied a place called Banes (possibly Baanes, the lake of Nikomedeia, but see Ramsay, Historical Geography, p. 159, who suggests that it was Baris, in Hellespontus) and cut off Harun 1's route back; later Antonios 1, Petros 8 and Staurakios 1 went to the Arab camp to negotiate a peace but failed to take precautions for their own safety and fell into the hands of Harun 1; a peace was finally reached favourable to the Arabs: Theoph. AM 6274. On the campaign of 782, see Treadgold, Revival, pp. 68-69. See also Rochow, Konstantin V, p. 206.
