Note 529 — Chapter VI · LUNAR CALENDARS AND THE WEEK

Horapollo, Hieroglyphica, i, 4; compare H. Brugsch, in Zeitschrift der deutschen morgenländischen Gesellschaft, 1856, x, 676; C. R. Lepsius, Die Chronologie der Ägypter, Berlin, 1849, i, 156 sq., 219; E. Meyer, “Ägyptische Chronologie,” Abhandlungen der königlich-preussischen Akademie der Wissenschaften, Berlin, 1904, pp. 5 sqq. Papyri discovered by Professor W. M. Flinders Petrie at Kahun, belonging to the age of Sesostris III, show that a lunar year of three hundred and fifty-five days was still recognized as late as the Twelfth Dynasty. These papyri relate to the temple revenues, which the priests, with characteristic religious conservatism, were accustomed to reckon according to lunar months (seven of thirty days and five of twenty-nine days). See L. Borchardt, in Zeitschrift für ägyptische Sprache, 1899, xxxvii, 92-95.
