Reptilian humanoids are a proposed race of intelligent, supernatural, or highly developed reptile-like humanoids in mythology, popular fiction, pseudoscientific theories and in the writings of New Age conspiracists. They appear in some conspiracy theories, most notably those of Riley Martin, John Rhodes, David Icke, and in science fiction. Reptoids, a conjoined word defining Reptilian-Humanoid beings, is the most popular name used to describe these cryptid beings, although some authors also refer to them as dinosauroids, lizardfolk or lizardmen. Other names include Draconians, Saurians and Sauroids. They are often described as being green or gold color. Similar to the other cryptids, no one has produced proof of the existence of reptilian humanoids, and allegations of their existence can at best be referred to as cryptozoology or pseudoscience.
In the Middle East, reptilian beings ranging from certain Jinn to dragons and serpent-men have been spoken of since ancient times. In one of the apocryphal books purporting to be the lost Book of Jasher, a serpent race is described.
In the Book of Genesis, God punishes the serpent for deceiving Eve into eating the fruit of the Tree of Knowledge of Good and Evil by decreeing, “Upon thy belly thou shalt go, and dust shalt thou eat all the days of your life” (Genesis 3:14 KJV). Traditionally, many have felt this implied that the serpent (a snake or reptile) had legs before then. Thus It is therefore often portrayed in Western art as a humanoid (woman) with a snake’s tail, and sometimes lizard-like feet, as in a detail from Bosch’s Last Judgement.
In the Middle Ages down to modern times, the Devil was often conceived as a humanoid with reptilian characteristics, as were demons in general. But the New Testament reference of Revelation 12:9 which identifies the serpent of Genesis as Satan himself (the “dragon, devil, Satan, ancient serpent,” etc.) gives insight from another angle. The serpent in the Garden of Eden was Satan himself, a beautiful supernatural being (either called a “serpent” symbolically, or because he manifested himself commonly in a dragon/serpent-like form). Hence the reference to “crawling” and “eating dust” is purely symbolic of his ultimate defeat and humiliation.
