Aryan root for both “Mother” and Measurement,” which gave rise to the English derivatives as matrix, matter, metric, material, maternal, matron, and so on. Matres meant the Celtic Triple Goddess, or Three Fates. Matri or “mothers” was a Tantric word for all benevolent female spirits. Matta, “Mother,” was the gypsies’ supreme Goddess, and an amalgam of many matriarchal titles. The Gnostic, Hermetic, or magical term for the Womb of Matter, matrix, was actually a redundant form meaning “she-mother” – mater with a feminine ending. A.G.H.
