Manual breue, y forma de administrar los santos sacramentos à los Indios.
A 1640 Spanish-language Catholic manual on administering the sacraments to Indigenous people, printed in Mexico City by Francisco Robledo and attributed to Martín de León, a Dominican. The pictures are small black-and-white woodcut printers' ornaments: a grotesque face framed by drapery and curling scrolls repeated across several versions, plus a decorated initial letter with foliage. A designer could draw on their bold carved line, symmetrical framing, and mask-like face for headers, borders, or dropcap treatments.
