https://en.wikipedia.org/wiki/Lepsius_list_of_pyramids
"The Lepsius list of pyramids is a list of sixty-seven Ancient Egyptian pyramids established in 1842–1843 by Karl Richard Lepsius (1810–1884), an Egyptologist and leader of the "Prussian expedition to Egypt" from 1842 until 1846.
The Lepsius list of pyramid is the first attempt at systematically listing all the Egyptian pyramids, and as such, is a pioneering effort of early modern Egyptology. The list was published together with the results of the expedition in Lepsius work Denkmäler aus Aegypten und Aethiopien (1849–1859)."
