Anonymus 785 was basilikos protospatharios ("protospatarius imperatoris"); in 833 he and Markos 7 were sent by the emperor Theophilos 5 as envoys to the Frankish ruler Lodoïchos 2; on arrival they found that Lodoïchos 2 had died and so they were presented instead to his successor, Lotharios 1; they apparently reported bad news about Theophilos 5 but no details are given; Lotharios 1 sent them back to Constantinople after the embassy: Astronomus, Vita Hludowici Imp. (ed. E. Tremp, MGH, Scr. Rer. Ger. in Usum Scholarum, Hanover, 1995) 49, p. 480 ("legatio Constantinopolitani imperatoris, Marcus archiepiscopus Ephesi et protospatarius imperatoris"; they described a "tragoediam"), cf. Annales Bertiniani (ed. G. Waitz, Scr. Rer. Ger. in Usum Scholarum, Hanover, 1883) s.a. 833, p. 7 ("legati ex Constantinopoli, qui ad patrem fuerant destinati, ad Hlotharium pervenerunt eique epistolas et munera detulerunt"; they reported "crimina" against the emperor).
