Leo 27 was also called Lalakon: Nicetas, Vita Ignatii 513B, Ps.-Symeon 668. He was domestikos of the Noumera in 858/859: Nicetas, Vita Ignatii 513B (Λέων ἐκεῖνος ὁ Λαλάκων ἐπονομαζόμενος τῶν Νουμέρων δομέστικος ὤν). When Ignatios 1 was driven from his see (in late 858) and persecuted by the Kaisar Bardas 5, Ignatios 1 was held for a time in the palace of Promotus in Constantinople, where Leo 27 was responsible for his custody; he once attacked Ignatios 1 and battered him about the face, dislodging two of his teeth: Nicetas, Vita Ignatii 513B, Ps.-Symeon 668.

Lalakon was a family name; see Winkelmann, Quellenstudien, pp. 169-170, and for two later members of the family, perhaps descendants of this man, see Schlumberger, Sig., p. 296, no. 6 = p. 671, nos. 1 (Leo Lalakon; tenth century), p. 671, no. 2 (Ioannes Lalakon; eleventh/twelfth century). Cf. also Leo 223. See Haldon, Byzantine Praetorians, p. 358, Seibt, Bleisiegel I 324.
