Kings of ancient time

Some scholars have argued that Osman's original name was Turkish, probably Atman or Ataman, and was only later changed to ʿOsmān, of Arabic origin. The earliest Byzantine sources, including Osman's contemporary and Greek historian George Pachymeres, spell his name as Ἀτουμάν (Atouman) or Ἀτμάν (Atman), whereas Greek sources regularly render both the Arabic form ʿUthmān and the Turkish version ʿOsmān with θ, τθ, or τσ. An early Arabic source mentioning him also writes ط rather than ث in one instance. Osman may thus have adopted the more prestigious Muslim name later in his life.[13] However Halil İnalcık argued that the hypothesis of Osman was named Ataman (per George Pachymeres), and came from the Desth-i Qipchaq, the north of the Black Sea, is a remote possibility.[14]
