Leonardo DaVinci's drawings of the Flower of Life, part of his Codex Atlanticus manuscript. It is a Sacred Geometry pattern based on Phi (The Golden Number) that can be found in music, nature and the genetic structure of humans, and that has been widely used in Greek, Jewish, Islamic, Persian, Egyptian, Chinese and Hindu art and religion. There are many beliefs and concepts associated to the Flower of Life; for example, depictions of the five Platonic Solids in Greek philosophy which are templates from which all life springs. Another example is the Tree of Life, a spiritual and philosophical symbol of the Jewish Kabbalah and the ancient Sumerians derived from the Flower of Life. The Vesica Piscis -which later on became the Fish symbol of Christianity also stems from it. The Temple of Osiris at Abydos, Egypt contains the oldest known examples of the Flower of Life. Suggestions that they are over 6,000 years old and may date back to as long ago as 10,500 B.C. One of the earliest known occurrences of the Vesica Piscis, and perhaps the first, was among the Pythagoreans. Components of the Flower of Life were also part of the work of the Medieval and Renaissance Alchemists, as a symbol of the golden, ascended consciousness in humanity which was what Alchemy truly sought for.
