Claim: Hermetica appeared in the 2nd-century Gnostic library another famous tract is the Emerald Tablet, thought that these texts were remnants of an extensive literature
Evidence: Parts of the Hermetica appeared in the 2nd-century Gnostic library found in Nag Hammadi. Other works in Syriac, Arabic, Coptic and other languages may also be termed Hermetica — another famous tract is the Emerald Tablet, which teaches the doctrine "as above, so below". For a long time, it was thought that these texts were remnants of an extensive literature, part of the syncretic cultural movement that also included the Neoplatonists of the Greco-Roman mysteries and late Orphic and Pythagorean literature and influenced Gnostic forms of the Abrahamic religions.
