Between 1595 and 1599 twenty-two books of lead were recovered from the sacred hillside of Sacromonte in Granada Spain, unearthed by treasure seekers no less.  These books were later determined forgeries, but it was not until the middle of the 19th century that most historians arrived at this conclusion. These plates were unearthed after the Moriscos were banished from Granada and forced to settle in France or North Africa. Moriscos were “nominally catholic descendants of Muslim converts,”  some of whom developed a hybrid of the two faiths. This amalgamation of Catholicism and Islam is found in the various translations of the lead books, supporting the Immaculate Conception, but reducing Jesus to a status outside the Trinity. It is believed that these documents were forged by Moriscos, not only for the purpose of “spiritual survival” and acceptance, but also to “exalt Granada above all the cities in Spain in holiness and antiquity.” 
One set of these plates contains a narrative that I find especially interesting and reminiscent of aspects related to Mormonism’s sacred metallic record—the Golden Plates. The leaden book titled A History of the Certainty of the Holy Gospel, describes Angel Gabriel visiting Mary in her home, and showing her a sacred record, “written by a powerful hand with radiant light on circular tables of precious stones, whose value God alone has knowledge of.” Mary transcribes the book on “leaden plates, sealed with the seal of Solomon,” and explains that God had ordered her to “do with [the plates] as was done with the tables of Moses; James will bear this copy to an uttermost quarter of the earth, and there he will conceal it in a holy spot where God shall guard it.” This sacred record would “remain under Gabriel’s protection until the heresies and offences of the world should need the application of the remedy; that those offences and heresies would be disclosed by the hand of a holy priest.” God will “raise up a lowly creature… who shall explain the Certainty of the gospel in the light of the Holy Ghost. When all are satisfied, their law shall become a single law, and error and impiety shall be banished from the world.” 
Mary gives the tablets and lead plates to Apostle James, saying, “Go with this copy of the tablets of the Certainty, and with this book, unto the seashore. God shall provide thee with a little boat, whose pilot shall be the angel Gabriel. When ye arrive in Spain… hide the book and tablets where the dead man comes to life.” James did as instructed, and as soon as he landed on the shores of Spain “and laid the book and tablets down, the earth began to gape, and from it came a man who said, ‘Why has thou raised me from my tomb, wherein I rested since the time of Moses?” The story ends by James taking these lead documents, records a history of his own of what had just taken place, and then deposits all of the records in a cave, to wait until the “great priest” shall arise and find them.
