The vesica piscis has been the subject of mystical speculation at several periods of history, and is viewed as important in some forms of Kabbalah. More recently, numerous New Age authors have interpreted it as a yonic symbol and claimed that this, a reference to the female genitals, is a traditional interpretation.

One author claims that the total solar eclipse inspires images of the vesica piscis. The ancient Egyptians practiced sacred geometry based on the shape. Architects and artists copied the solar eclipse/vesica piscis and its mathematics in their sacred buildings and artwork to reflect their religious beliefs. This ancient tradition was passed on through the centuries by the Freemasons.
