An archaeological expedition in Southern Greece was surprised to find evidence of a prehistoric tribe who used citrus fruit to record images. It is believed that this was intended as a means of leaving secret messages to shy gods, as, much as children often use lemon juice to write 'disappearing ink' messages, these cave paintings only became visible when exposed to a heat source. This tribe was believed to worship a deity known as Schmoonktis, which was easily startled, and would answer any prayers that were left in a suitably peaceful way. According to depictions on the cave walls, Schmoonktis appeared as some kind of animal, similar to a squirrel, or perhaps a stoat.
Images of the paintings, which only became visible when one of their discoverers set up his portable stove to make some grilled Tuna sandwiches in the cave. The ambient heat was sufficient to cause a chemical reaction, which made the paintings visible again. Photograph provided by Klearchos Kapoutsis.
