Anonymus 164 was a protospatharios and epi tou chrysotriklinou; owner of a seal dateable to the ninth century (Schlumberger gives eighth or ninth, probably too early for seals of this office): Schlumberger, Sig., p. 468, no. 4. Obv.: cruciform monogram of Κύριε βοήθει with τω - σω - δου - λω in the corners. Rev.: cruciform monogram of the owner's name, with the letters of πρωτοσπαθ[αρίῳ] καὶ ἐπὶ τ[οῦ] χρ[υσο]τρ[ι]κ[λίνου] in the quarters. Schlumberger gives no facsimile or other indication of the letters on the monogram, which he was unable to decipher (does this mean that the letters were illegible or that he could not solve the monogram?). The seal was in Schlumberger's own collection.
