In 1945 peasants working at Nag Hammadi in Upper Egypt discovered the famous Coptic Gnostic Library of sacred books, which had lain concealed in earthenware jars for fifteen centuries. Among them was the Apocalypse of Adam -- the Book with Fourteen Seals. Welburn presents here the results of his investigation into this remarkable document and shows how its message can be read once more. Looking back to the beginnings of human history, it points to fulfillment of the ancient Mysteries in the appearance of the Light on earth, the Christ-Revelation.
