Hethara 8/October 7
At various times of the year, the god or goddess of a temple would follow a sacred pathway to another temple to 'visit' the diety dwelling there. This particular date is The Going-Forth of Isis. A procession would take an image, usually the most extravagent one of Isis in temple, and would carefully follow a route to another temple. Stops were usually made on the way there, where the Priestesses and Priests would preform divination and a brief public rite. Finally, the procession would arrive at the second temple, and the image of Isis would be placed in an honored location, with a festival held at the second temple as well.
Tahuti 1/August 1
This was marked by the rising of the Nile, raised by the tears of Isis. Gifts were often exchanged, and entertainment was to be found everywhere in Egypt. There were plays preformed in the temples to honor their gods.
