The story of Dhul-Qarnayn (in [[Arabic]] ذو القرنين, literally "The Two-Horned One", also transliterated as Zul-Qarnain or Zulqarnain) is found in the 18<sup>th</sup> [[Surah]] of the Qur'an, al-Kahf (the Cave).  While he is never mentioned explicitly by name, the story is clearly based upon a legendary account of Alexander the Great.  For centuries, most Muslim historians and Qur'anic commentators endorsed the identity of Dhul-Qarnayn as Alexander, though some also proposed alternatives. In recent years, this identification of Dhul-Qarnayn has become particularly problematic and controversial for Muslim scholars, as the Qur'an's understanding of Alexander differs remarkably from the image of him in history as a Greek [[Pagan Origins of Islam|pagan]] who fashioned himself as a [[god]]. This has prompted some [[apologists]] to create and advance alternative theories that identify  Dhul-Qarnayn as other prominent historical kings, most notably Cyrus the Great. These alternative theories, though, have major deficiencies and fall short of the strong parallels between the Qur'anic story and legends of Alexander that date to the early 7<sup>th</sup> century. The theory that Dhul-Qarnayn is some other figure such as Cyrus the Great has little evidence in its favor compared to the overwhelming evidence that the story is actually based on a legendary version of Alexander. The story in the Qur'an in fact parallels a medieval Syriac legend of Alexander quote closely; both narratives portray him as a believing king who traveled the world and built a barrier of iron which holds back the tribes of Gog and Magog until Judgement Day. Almost every major element of the Qur'anic story can be found in Christian and Jewish folklore about Alexander which dates back hundreds of years prior to the time of Prophet Muhammad. Most early Muslim commentators and scholars identified Dhul-Qarnayn as Alexander the Great, and some modern ones do too. Historical and Archaeological evidence, though, quite plainly reveal that the real Alexander was a polytheistic pagan who believed he was the literal son of Greek and Egyptian gods. In addition, the story speaks of a giant wall built by Dhul-Qarnayn to hold back the nations of Gog and Magog, yet today, there is no such giant wall of iron and brass between two mountains that is holding back a tribe of people; it likely never existed and was originally a legendary embellishment of the original Alexander legend.
