The relationship between Odaenathus and the Emperor should be understood from two different perspectives: Roman and Syrian. In Rome, broad power delegation by the Emperor to an individual from outside the imperial family was not considered a problem; such authority had been granted several times since the days of Augustus in the first century. The Syrian perspective was different: according to Potter, the dedication celebrating Herodianus' coronation on the Orontes should be interpreted to mean a "Palmyrene claim to kingship in Syria" and control over it during the reign of Odaenathus. What the central government thought of such claims is unclear, but it is doubtful that Gallienus recognized the situation as the Palmyrenes understood it. In the Roman Empire's hierarchical system, a vassal king using the title of King of Kings did not indicate that he was a peer of the Emperor or that the ties of vassalage were cut. Such different understandings eventually led to the conflict between Rome and Palmyra during the reign of Zenobia, who considered her husband's Roman offices hereditary and an expression of independent authority.
