The Hidden Science of Drawing at Pictures

Picatrix is an entire course in the forbidden science of drawing at pictures. Here are the standard images that you should paint when the moon is between this degree and that degree. This is the picture that you draw in order to create an icon to worship this planet or engage this planet in magical activity. And then the picture does the magic for you. The picture is the spell. So a lot of magic in Picatrix works that way. There's a lot of other magic, which is alchemical. Some of those recipes generate poisons. Clouds of poison. Oh, look, the spell for eternal life generates a death-dealing poison. Maybe you shouldn't use that one.
