Konstantinos 12 was described as ὁ τοῦ βικαρίου; he was a spatharios and domestikos of the Exkoubitores in late 780 (Κωνσταντῖνός τε, ὁ τοῦ βικαρίου σπαθάριος καὶ δομέστικος τῶν ἐκσκουβιτόρων: Theoph. AM 6273); he was one of the leaders of a conspiracy formed in October 780 against the new emperor Constantine VI (Konstantinos 8) and his mother Eirene 1, which aimed to put Nikephoros 5 on the throne; he was one of those arrested, beaten and tonsured and sent into exile: Theoph. AM 6273. See Gregorios 11.
Bikarios is perhaps a personal name and denotes the father of Konstantinos 12; see Bikarios 1, but on the problem of bikarios as a name or title, cf. Theodoros 10.
On Konstantinos 12, cf. Haldon, Byzantine Praetorians, pp. 355-356 with p. 622, n. 1071. He was probably a domestikos of the Exkoubitores with the dignity of spatharios.
