Charles Godfrey Leland

“ As the orange was the fruit of the Sun, so is the lemon suggestive of the Moon or Diana, its colour being of the lighter yellow. However, the lemon specially chosen for the charm is always a green one, because it "sets hard" and turns black. It is not generally known that orange and lemon peel, subjected to pressure and combined with an adhesive may be made into a hard substance which can be moulded or used for many purposes. ”

“ I'll wait for thee, bearing a cup of wine,
Therewith a lens or a small burning-glass. [2]
And thirteen pins I'll put into the charm;
Those which I put shall all indeed be black,
But thou, Diana, thou wilt place them all! ”

“ A lemon stuck full of pins of different colours always brings good fortune.
If you receive as a gift a lemon full of pins of divers colours, without any black ones among them, it signifies that your life will be perfectly happy and prosperous and joyful.
But if some black pins are among them, you may enjoy good fortune and health, yet mingled with troubles which may be of small account. (However, to lessen their influence, you must perform the following ceremony, and pronounce this incantation, wherein all is also described. [1] )
The Incantation to Diana. ”
