La dialectique [microforme]
A 1673 Paris logic treatise, La dialectique, by Gilles de Launay and published by C. Barbin, likely written for students of philosophy. Its three pictures are a small printed ornamental strip of a winged bird flanked by scrolling foliage, repeated twice, and a page fragment of a hanging tabular diagram with brace marks and French text labels, which suggests a designer could borrow the cartouche-style border and the bracketed chart layout for historical typographic framing.
