Athanasii Kircheri... Magnes sive de arte magnetica : opus tripartitum quo praeterquam quod universa magnetis natura, eiusque in omnibus artibus & scientiis usus nova methodo explicetur, e viribus quoque & prodigiosis effectibus magneticarum, aliarumque abditarum naturae motionum in elementis, lapidibus, plantis & animalibus elucescentium, multa hucusque incognita naturae arcana per physica, medica, chymica & mathematica omnis generis experimenta recluduntur
Athanasius Kircher's Magnes sive de arte magnetica, a Latin treatise on magnetism printed in 1643 by Iodocus Kalcoven, written for scholars and natural philosophers of the seventeenth century. Its pictures are engraved diagrams: ribboned cartouches framing horoscope-style dial plans, a magnetic globe on a stand, and a pivoting disc, drawn in fine black line on plain paper, which a designer might take as a model for compass-rose and astrolabe-style linework.
