Book of Amun-Ra

The Book of Amun-Ra was an Ancient Egyptian book made of pure gold.

Known colloquially as "the Book of the Living” or "the Golden Book", the Book of Amun-Ra contained ancient spells and incantations that could take life away from mortals. To keep it safe from interference from unworthy men, the ancient Egyptians kept the Book inside a statue of Horus at Hamunaptra, where it was declared forbidden to use. The Book of Amun-Ra was fashioned so that only one with a "key" might open it: indeed, the Book had a small puzzle-box-like object that, when opened, acted as the key with which to open the Book.
