Souvenir Series #4
On a recent trip to Mexico I found this modern obsidian mirror in a craft market in Mexico City. Obsidian mirrors were made and prized by the Aztecs (Mexica) for their supposed healing and divination properties. They are still made today, mainly for the tourist market. I visited an obsidian workshop near Teotihuacan and saw how the black volcanic glass is cut and polished. Obsidian is commonly black but it can also occur with red or green hues depending on its mineral content, and it fractures much like flint, meaning it can be knapped into tools and ornaments – it was commonly used in this way by many Mesoamerican cultures.
In Aztec times obsidian mirrors, much the same shape as this one, were associated with the God Tezcatlipoca, who had many associations – notably with the night sky and with sorcery. His name can be translated as “Smoking Mirror.” Contemporary Spanish chroniclers have described how such mirrors were used by the Aztecs in rituals to communicate with the underworld and also to foretell future events. It was said that the last Aztec ruler, Moctezuma II (c.1466-1520), predicted the coming of the Spanish Conquistadors and the destruction of his empire from an omen which he witnessed in a mirror.
Many of these magical obsidian mirrors were sent or brought back to Europe during the 16th Century and became highly prized artefacts amongst the learned aristocracy. Perhaps the most notable of these is the Aztec mirror which made its way into the possession of the English Elizabethan Magus, Dr John Dee (1527-1609), now in the British Museum.
Dr Dee is perhaps most commonly remembered for his mystical dabblings in alchemy, sacred geometry, and, in particular, for his efforts to communicate with angels. He is also thought to have been the possible inspiration for the character of Prospero in William Shakespeare’s The Tempest.
Dee used his obsidian mirror, along with other occult implements which he described as his “scrying stones” to perform séances which he believed would help him to achieve a deeper and more enlightened understanding of the manifold and mysterious workings of the universe. Scrying, as perceived by Dee, was in this sense an ‘optical science’ – which, if conducted piously and devoutly, was a sacred act not to be confused with the dark arts of the common conjuror or a ‘caller of devils.’ Indeed, the historian Frances Yates (1899-1981) has described Dee as a ‘Christian Cabbalist.’ A learned and scholarly man devoutly seeking to understand the truth of God’s manifest will codified and hidden in the wonders of creation. To this end he mixed the fundamental tenets of astronomy, astrology, alchemy, magic, mathematics, mechanics, and other methods of scientific mysticism or critical enquiry to achieve a higher knowledge, yet it was a dangerous vocation, and so Dee – although a familiar and close confidante of Queen Elizabeth I herself – prudently sought to veil his potentially blasphemous and heretical activities in secrecy.
Dr Dee is perhaps most commonly remembered for his mystical dabblings in alchemy, sacred geometry, and, in particular, for his efforts to communicate with angels. He is also thought to have been the possible inspiration for the character of Prospero in William Shakespeare’s The Tempest.
