“Ariadne is the thread of alchemy, the guiding principle of the art of chemistry, the Theseus of the artist, leading to the mastery of the work; especially the method of preparing the Philosophers’ Mercury, without which nothing can be accomplished or produced in the transmutatory art. The bull, however, is our matter, from which we extract the mercury and the sulfur of the philosophers.” - Johann Friedrich Rain, Theoria et praxis lapidis philosophorum (Theory and Practice of the Philosopher's Stone)
Ariadne’s thread is the thread of the divine present in all things. If one could find the beginning of the thread within, they could then unravel it and discover, or rather uncover, their source.
