This name derives from the Ancient Greek “*Di̯ēus > Zefs > Zeús (Ζεύς) bía (βία) Bías (βίας) Zēnóbios (Ζηνόβιος)”, meaning “the force of Zeus”. Zenobia (~240–274) was a 3rd-century Queen of the Palmyrene Empire in Roman Syria. She led a famous revolt against the Roman Empire. The second wife of King Septimius Odaenathus, Zenobia became queen of the Palmyrene Empire following Odaenathus' death in 267. By 269, Zenobia had expanded the empire, conquering Egypt and expelling the Roman prefect, Tenagino Probus, who was beheaded after he led an attempt to recapture the territory. Saint Zenobius (337–417) is venerated as the first bishop of Florence. His feast day is celebrated on May 25.
