This shirt for Black Vulture Gallery is based on a spell from the Grimoirium Verum. “Begin this operation on a Wednesday before the sun rises, being furnished with seven black beans. Take next the head of a dead man; place one of the beans in his mouth, two in his eyes and two in his ears. Then make upon this head the character of the figure which here follows. (Omitted in all the Grimoires.) This done, inter the head with the face towards heaven, and every day before sunrise, for the space of nine days, water it with excellent brandy. On the eighth day you will find the cited spirit, who will say unto you: What doest thou? You shall reply: I am watering my plant. He will then say: Give me that bottle; I will water it myself. You will answer by refusing, and he will again ask you, but you will persist in declining, until he shall stretch forth his hand and shew you the same figure which you have traced upon the head suspended from the tips of his fingers. In this case you may be assured that it is really the spirit of the head, because another might take you unawares, which would bring you evil, and further, your operation would be unfruitful. When you have given him your phial, he will water the head and depart. On the morrow, which is the ninth day, you shall return and will find your beans ripe. Take them, place one in your mouth, and then look at yourself in a glass. If you cannot see yourself, it is good. Do the same with the rest, or they may be tested in the mouth of a child. All those which do not answer must be interred with the head.” So maybe this shirt will make you invisible.
