““Kabbalah (in Hebrew, literally “receiving”) refers to the mystical traditions that encompass the secrets of the Torah, the esoteric truths that reveal the most profound understanding of the world, of humankind, and of the Almighty himself. Philo was a Jewish mystic in Alexandria, Egypt, who wrote dissertations on the Kabbalah in the first century of the Christian era. He is commonly considered the central link between Greek philosophy, Judaism, and Christian mysticism. His triangles point either up or down to show the flow of energy between action and reception, male and female, God and humanity, and the upper and lower worlds. In fact, the Latin name for this kind of mosaic decor is opus alexandrinum (Alexandrian work) because it is filled with Kabbalistic symbolism originally taught by Philo of Alexandria.””
