Azoth In Alchemy, a name for MERCURY, especially the hypothetical “mercury of the philosophers,” or the spiritual essence of mercury. Azoth is a corruption of the Arabic word for mercury, al-zauq. It was considered to have great occult powers because it contains both the first and last letters of the Greek, Roman, Hebrew, and Arabic alphabets. Azoth also is a name for celestial dew. A woodcut of Paracelsus shows him holding a roundheaded staff bearing the name Azoth.
