Leviathan, sive, De materia, forma, & potestate civitatis ecclesiasticae et civilis
Thomas Hobbes's Leviathan, a 1668 political treatise printed in Amsterdam by Joan Blaeu, written in Latin for scholarly readers of state and church. Its pictures are small decorative headpieces of scrolling foliage around a central figure, a woven initial letter, and a black silhouette portrait, useful to designers for ornamental borders, framing devices, and period lettering.
