De canonicis, et dignitatibus, aliisque inferioribus beneficiariis cathedralium & collegiatarum ecclesiarum, eorúmque officio tam in choro, quàm in capitulo : elegans et perutilis tractatus
A Latin treatise on cathedral and collegiate canons and their offices, written by Agostinho Barbosa (1590-1649) and printed in Lyon in 1634 for churchmen and clergy. Its pictures are small woodcut decorative initials: the first shows a winged, mermaid-like figure pair flanking a tall letter I, while the N initials use interlaced foliage, scrolls and a grotesque face, offering a designer ready-made early modern ornamental letterforms to adapt.
