Anonymus 547 was a basilikos spatharios and protonotarios of the Boukellarioi; owner of a seal dateable to the second half of the ninth century; his name is lost but ended with the letters ος: Zacos and Veglery 2654. Obv.: cruciform monogram of Θεοτόκε βοήθει, with .ω - σω - δου - λω in the corners. Rev.: ..... - ω β' σπαθ' και .. - νοταρι' των - Βουκελ. . The betas are in the form of a Latin capital R, and so the date is not before the early to mid ninth century. The name and titles read: ... ῳ βασιλικῷ σπαθαρίῳ καὶ πρωτονοταρίῳ τῶν Βουκελλαρίων.
