Parergon, in alchemy, was a term designating the left eye of the soul, which was turned toward time. This was opposed to the right eye of the soul, ergon, which was directed toward eternity.

Here is seen the religious aspect of alchemy, left toward the sinister and right toward the divine. After failing in purifying metals into gold alchemy tried purifying man.
