Elegant ‘A’ from Art and Architecture Manifesto. Published 1989, designed by Pentagram (via ZsaZsa Bellagio)
a, chapter beginning of a printed edition of Aristotle's De animalibus (1476) (via Ptak Science Books "At first glance it looks like it might be an attempt at design/spacing, an illustration in a modern Dadaist vein, capturing space and attention while using hardly anything at all, a simple floating letter, an intentional placement of an object in an unusual field. It is that, in a very minor way, but the attention-getting device was used to gather up the focus of only one person. The little "a" is simply a place-holder, waiting for the the next stage in production of the book, for the rubricator to come in and decorate the space with a magnificent/articulated/flourishing capital "A", which was the practice of this time."
