A collection of thirteen ancient codices containing over fifty Philosophical and religious texts were discovered in Upper
Egypt
in 1945 . In December of that year , two Egyptian brothers found several papyri in a large earthenware vessel while digging for fertilizer around limestone caves near the modern city Hamra Dom (in Upper Egypt); then they began to sell them piece by piece . Now , the codices are in the Coptic Museum in Cairo .
These codices include a large number of primary Gnostic scriptures- texts once thought to have been entirely destroyed during the early Christian struggle to define Orthodoxy . They contain scriptures such as the Gospel of Thomas , the Gospel of Philip , and the Gospel of Truth . These texts have been translated to various languages and are still regarded as a highly important Coptic texts to be found dating back to the second century BC .
