This name derives from the Ancient Greek name “Dioklês (Διοκλῆς)”, composed of two elements: “Zeús (Ζεύς) Días (Δίας)” (Zeus) plus “kléos (κλέος)” (rumor, report, good report, fame, glory). In turn, the name means “glory of Zeus, glory to Zeus”. The name has spread from the Latin “Dĭŏclētĭānus” (Ancient Greek: Dioklētiānós ”Διοκλητιᾱνός”). Diocletian was a Roman Emperor from 284 to 305. Born to a family of low status in the Roman province of Dalmatia, Diocletian rose through the ranks of the military to become cavalry commander to Emperor Carus. After the deaths of Carus and his son Numerian on campaign in Persia, Diocletian was proclaimed Emperor.
