Paracelsus, Coelum philosophorum
Recipe: Salt nitre, four ounces; a moiety of sulphur; tartar, one ounce. Mix and liquefy.
I am dark and bright; I spring from the earth and I come out of heaven. I am well known and yet a mere nothing. All colours shine in me and all metals by the beams of the sun.
I am the Carbuncle of the Sun.
-Thomas Vaughen, Coelum Terra.
Matter — as I have formerly intimated — is the house of light.
-Thomas Vaughen, Aula Lucis
