Natural magick,
Natural Magick is a 1658 London scientific treatise by the Neapolitan natural philosopher Giambattista della Porta, printed for the booksellers T. Young and S. Speed for readers of experimental science and the industrial arts. Its pictures are small woodcut decorated initial letters framed in strapwork and foliage, plus a few diagrams of stone-like shapes, which a designer could draw on for ornamental capitals, border patterns, and hatched line work.
