BABYLONIAN GRAMMATICAL TEXT STONE (used in the research and assembly of a dictionary of the language of ancient Mesopotamia and its Babylonian and Assyrian dialects, both unspoken for years, preserved on clay tablets and in stone inscriptions)
The Codex Gigas. The largest medieval manuscript in existence. Written by a single scribe in the century. Sometimes called The Devil's Bible because of the large, unexplained picture of Satan in the middle of the book.
