The Theatrum Chemicum Britannicum (1652) remains a valuable historical source for understanding the role of alchemy in shaping the foundations of modern science and chemistry. The shirt features the symbol for Foras, a powerful demon who teaches hermetics, including the application of herbs and precious stones in sorcery. 

"Solve Et coagula" is the fundemental alchemical principle meaning to "dissolve and coagulate." A substance must be broken down into its base elements before it can be built up into something new. Solve refers to this breaking down of elements and coagula refers to their coming together. It's a phrase that implies renewal and transformation.
