Idea de vn principe politico christiano, rapresentada en cien empresas
A 1642 Spanish emblem book, Idea de vn principe politico christiano, by Diego de Saavedra Fajardo with engravings by Giovanni Paolo Bianchi, offering a hundred political devices for the education of Christian princes. Its pictures are framed cartouches with Latin mottoes such as IN HOC SIGNO, AUSPICE DEO and LIBRATA REFULGET, each engraved in fine line around a central emblem like a banner, sprig, sceptre or sphere. A designer could borrow the ornate scrolled frames and motto banners as sources for heraldic or title-page borders.
