Caliphate

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The reader will bear in mind that the Moslem year, as purely lunar, is eleven days shorter than the solar, and consequently loses about three years in every cycle of a hundred. The lunar month has also this peculiarity, that while, like the Jewish, the date indicates the age Of the moon, the month itself gives no indication Of the season Of the year. The dates have usually been given throughout according to both the Moslem and the Christian notation.
