Where two circles overlap, a doorway opens — the almond through which all shapes are born.
The Form
The Vesica Piscis is the shape formed where two circles of equal radius overlap so that each passes through the center of the other. The lens-shaped region of their intersection — pointed at both ends, swollen in the middle, the almond or fish that gives the figure its name — is the simplest of all generated forms, requiring only two circles and a single relationship between them. Yet from that meager beginning an enormous amount follows. The two centers and the two points of intersection form the vertices of two equilateral triangles; the width and height of the lens stand in ratios that encode the square roots of three and other root proportions fundamental to geometry.
Because it arises the moment one circle is repeated beside another, the Vesica Piscis appears at the first overlap of the Seed of Life and reappears throughout the Flower of Life. It is the seam where duplication becomes generation, the crossing that turns two circles into the seed of every straight-edged figure to come.

Meaning
The Vesica Piscis is read almost universally as a womb and a threshold, the space between two circles where new form gestates. It is the union of opposites — two identical worlds overlapping to bring forth a third region that belongs to neither alone — and from that region the triangle and the sacred ratios are drawn, making it the mother of the geometric figures. In Alchemy the joining of two into a fertile third is the very grammar of the work, the conjunction from which the new substance issues. As the first overlap within the Flower of Life, the Vesica Piscis is where multiplicity is conceived, the doorway between the one and the many.
