The term Grimoire comes from an old French word that referred to any text written in Latin. The new meaning is believed to date back to the medieval period when pagans were being persecuted. The books of herbal remedies, worship of gods and goddesses, and other aspects of pagan life at this time were used as secret journals. Nowadays, grimoires are used in the same way, they act as a journal. It is considered bad luck to show the inside of your grimoire to anyone, but they are usually filled with recipes, spells, herbal associations, crystal grids, and more. It is used as a collection of all the knowledge gained through practice.
