The Single Monad Model of the Cosmos

Ibn Arabi distinguishes between the witnessed lunar month, which is from new moon to another new moon, and the 'divine Month' which is the time needed for the moon to perform one full revolution in the orb of the zodiac: that is, as Ibn Arabi says, twenty-eight days [III.548.28]. He also recognizes the solar 'month' as the sun's observed motion throughout the zodiac, where the zodiac is conventionally divided into twelve parts, each corresponding to one month [I.388.20], though he does not give any details about the length of solar months in terms of their days.[56]
