Isis Rises — Lady Of Assumption
In typical Egyptian story form, Isis finished her crying over her soul mate Osiris in about the middle of August, which means that Isis cried all the tears she had. It is at this point in time that the Egyptians (both ancient and modern) hold a festival signifying the last teardrop from Isis which will cause the peak of the flood level. It is during this celebration that the Egyptians throw an effigy of Isis into the waters, to symbolize that Isis drowned in her own tears. Incredibly, the church has adopted the same exact date to represent the ascension of the “Virgin Mary” to heaven as Assumption Day, which is defined as:
The dogma of the taking up of the body and soul of the Virgin Mary (Auset is also a virgin) into heavens after her death.
The Orthodox Church celebrates Assumption Day on 15 August, which is the same exact day when present-day Egyptians observe the end of the rainy season in Ethiopia.
In addition to official governmental celebrations, the Baladi Egyptians hold a mouled called Sitena Meriam (meaning Our Lady Meriam). This is not a “Christian festival”. The festival lasts the typical Egyptian octave-week (8 days). The last day of the celebration is 16 Mesoree (22 August).
Another title for this festival is Bride of the Nile, uniting Isis with Osiris. Isis has submerged—as a symbol of earth—in her husband’s body—a symbol of water. This unification is another perfect application of the concept of inner marriage that permeates Ancient Egyptian (and later Sufi) traditions.
=> It should be noted that from 3 July (the beginning of the rise of the Nile waters) to 22 August is 50 days—another Pentecost.
