Adamant in classical mythology is an archaic form of diamond. In fact, the English word diamond is ultimately derived from adamas, via Late Latindiamas and Old Frenchdiamant. In ancient Greek ἀδάμας (adamas), genitive ἀδάμαντος (adamantos), literally 'unconquerable, untameable'. In those days, the qualities of hard metal (probably steel) were attributed to it, and adamant became an independent concept as a result.
In the Middle Ages adamant also became confused with the magnetic rock lodestone, and a folk etymology connected it with the Latin adamare, 'to love or be attached to'.[1] Another connection was the belief that adamant (the diamond definition) could block the effects of a magnet. This was addressed in chapter III of Pseudodoxia Epidemica, for instance.
Since the contemporary word diamond is now used for the hardest gemstone, the increasingly archaic noun adamant has been reduced to mostly poetic or anachronistic use. In that capacity, the name, and various derivatives of it, are frequently used in modern media to refer to a variety of fictional substances.
In Greek mythology, Cronus castrated his father Uranus using an adamant sickle given to him by his mother Gaia.[4] An adamantine sickle or sword was also used by the hero Perseus to decapitate the Gorgon Medusa while she slept.

In Virgil's Aeneid, the gate of Tartarus is framed with pillars of solid adamant, "that no might of man, nay, not even the sons of heaven, could uproot in war"[5]
In John Milton's epic poem Paradise Lost, adamant or adamantine is mentioned eight times. First in Book 1, Satan is hurled "to bottomless perdition, there to dwell in adamantine chains and penal fire" (lines 47–48). Three times in Book 2 the gates of hell are described as being made of adamantine (lines 436, 646 and 853). In Book 6, Satan "Came towring [sic], armd [sic] in Adamant and Gold" (line 110), his shield is described as "of tenfold adamant" (line 255), and the armor worn by the fallen angels is described as "adamantine" (line 542). Finally in book 10 the metaphorical "Pinns [sic] of Adamant and Chains" (lines 318–319) bind the world to Satan, and thus to sin and death.[6]
In The Hypostasis of the Archons, Gnostic scripture from the Nag Hammadi Library refers to the Adamantine Land, an incorruptible place 'above' from whence the spirit came to dwell within man so that he became Adam, he who moves upon the ground with a living soul.[7]
