52 Copies of the decree in hieroglyphic, demotic, and Greek have been found inscribed on stones in Egypt. See Ch. Michel, _Recueil d’Inscriptions Grecques_ (Brussels, 1900), pp. 415 _sqq._, No. 551; W. Dittenberger, _Orientis Graeci Inscriptiones Selectae_ (Leipsic, 1903-1905), vol. i. pp. 91 _sqq._, No. 56; J. P. Mahaffy, _The Empire of the Ptolemies_ (London, 1895), pp. 205 _sqq._, 226 _sqq._ The star mentioned in the decree is the Dog-star (Sirius). See below, pp. 34 _sqq._ 53 W.

M24 Institution of the fixed Alexandrian year by the Romans. 54 On the Alexandrian year see L. Ideler, _Handbuch der mathematischen und technischen Chronologie_, i. 140 _sqq._ That admirable chronologer argued (pp. 153-161) that the innovation was introduced not, as had been commonly supposed, in 25 B.C., but in 30 B.C., the year in which Augustus defeated Mark Antony under the walls of Alexandria and captured the city. However, the question seems to be still unsettled. See F. K. Ginzel, _Handbuch der mathematischen und technischen Chronologie_, i. 226 _sqq._, who thinks it probable that the change was made in 26 B.C. For the purposes of this study the precise date of the introduction of the Alexandrian year is not material. 55 In demotic the fixed Alexandrian year is called “the year of the Ionians,” while the old movable year is styled “the year of the Egyptians.” Documents have been found which are dated by the day and the month of both years.
