Romanos 9 was a basilikos protospatharios and domestikos of the Teiche; owner of a seal dateable to the second half of the ninth century: Zacos II 283. Obv.: patriarchal cross on base and two steps with the legend +Κ(ύρι)ε βοήθει τῷ σῷ δούλ(ωι)+. Rev.: +Ρομαν - ο β' α' σπαθ - αρηο και δομ - εστ' τον τ - ηχεον. The text reads: Ῥωμανῷ βασιλικῷ πρωτοσπαθαρίῳ καὶ δομεστίκῳ τῶν τειχέων. Two very similar seals, presumably belonging to the same person, are preserved, one in the Dumbarton Oaks Collection, no. 1296, and the other in the Fogg Museum of Art, no. 376.
