Another source of chronological information is the so-called “Palermo Stone,” which is preserved in the Museum of Palermo, Sicily. This stone is a hard diorite, and is but a fragment of the original. It was inscribed about the middle of the fifth dynasty, and originally contained a list of the kings of Egypt from a time long before Mena to the middle of the fifth dynasty. Though now but a fragment, it is still of great value for the period which it covers. In addition to this, we also have the King List of Karnak, set up by Thothmes III, of the eighteenth dynasty, the King List of Abydos, inscribed by Seti I and Ramses II, of the nineteenth dynasty, and the King List of Sakkarah, inscribed by Ramses II. As these are all simply selections from the list of the predecessors of their authors, they are of secondary importance. The “Turin Papyrus” would be of value chronologically, but for its unfortunate history. This papyrus originally contained the most complete list of Egyptian kings that has come down to us, with the exception of Manetho’s chronology. It formed part of the collection of M. Drovetti, the French Consul-General in Egypt. The collection was offered to the French government in 1818, but was finally purchased by the king of Sardinia. When the collection arrived in Turin, it was found that this papyrus was broken into small fragments in the bottom of the box in which it had been shipped. The fragments were afterward (1824) examined by Champollion the younger, who discovered their true character. In 1826 another Egyptologist went to Turin and joined the fragments; but the science of Egyptology was then in its infancy, and he in his ignorance joined pieces which did not naturally belong together. For this reason it is only occasionally that the document yields us any chronological data.
