Page "Isis" Paragraph 21

Little information on Egyptian rituals for Isis survives ; however, it is clear there were both priests and priestesses officiating at her cult throughout its history.

By the Greco-Roman era, many of them were considered healers, and were said to have other special powers, including dream interpretation and the ability to control the weather, which they did by braiding or not combing their hair.

The latter was believed because the Egyptians considered knots to have magical powers.
