Alchemical Sulfur

The Combustible Principle

An alchemical sign for sulphur: a triangle above a cross.

What it meansIn Paracelsus's Opus Paramirum, sulphur is what burns. Different bodily substances have different sulphurs, which can be revealed and distinguished through separation.

The FindingIn 1531 Paracelsus distinguished many sulphurs: blood, flesh and organs each have their own, rather than sharing one universal combustible substance.
