Papyrus Carlsberg 1 is inscribed with a fundamental treatise on the celestial bodies known as the Book of Nut, second century AD. The Tebtunis temple library held several versions of the text, which is first attested nearly 1,500 years earlier in the reign of Sety I where it was engraved in stone in the underground temple of Osiris at Abydos. A master version from the library was written in hieroglyphs and included detailed illustrations, while other simpler versions contained only the text and were written in the hieratic script. The version here shown contains both the original text in the hieratic script and later commentary on the ancient composition written in demotic. Acquired 1931 by the Carlsberg Foundation.
