Two treatises: in the one of which, the nature of bodies; in the other, the nature of mans soule, is looked into: in way of discovery of the immortality of reasonable soules
A 1658 London philosophical treatise by Kenelm Digby, printed for John Williams, on the nature of bodies and of the soul. Its pages are dense black-letter text set around small geometric diagrams, with lettered points A through L joined by straight lines. A designer could take from them the plain, schematic look of early modern scientific figures, with labelled lines and capital letters set against open paper.
