Ramon Llull (1232–1315) wrote a Liber Chaos, in which he identifies Chaos as the primal form or matter created by God. Swiss alchemist Paracelsus (1493–1541) uses chaos synonymously with "classical element" (because the primeval chaos is imagined as a formless congestion of all elements). Paracelsus thus identifies Earth as "the chaos of the gnomi", i.e., the element of the gnomes, through which these spirits move unobstructed as fish do through water, or birds through air.[39] An alchemical treatise by Heinrich Khunrath, printed in Frankfurt in 1708, was entitled Chaos.[40] The 1708 introduction states that the treatise was written in 1597 in Magdeburg, in the author's 23rd year of practicing alchemy.[41] The treatise purports to quote Paracelsus on the point that "The light of the soul, by the will of the Triune God, made all earthly things appear from the primal Chaos."[42] Martin Ruland the Younger, in his 1612 Lexicon Alchemiae, states, "A crude mixture of matter or another name for Materia Prima is Chaos, as it is in the Beginning."
