The first inscription mentioning Zenobia as queen is dated two or three years after Odaenathus' death, so exactly when Zenobia assumed the title "queen of Palmyra" is uncertain. However, she was probably designated as queen when her husband became king. As queen consort, Zenobia remained in the background and was not mentioned in the historical record. According to later accounts, including one by Giovanni Boccaccio, she accompanied her husband on his campaigns. If the accounts of her accompanying her husband are true, according to Southern, Zenobia would have boosted the morale of the soldiers and gained political influence, which she needed in her later career.
