La geometrie, redvite en vne facile et briefve practique, par deux excellens instrumens, dont l'vn est le pantometre ov compas de proportion
A 1626 Paris geometry treatise by Michiel Coignet, published by Charles Hulpeau, presenting a practical method using a proportional compass (pantometre) for students and practical surveyors. The pictures are plain line diagrams in brown ink on cream paper: a polygon inscribed in a circle, a circle with a diameter and labelled points, a triangle with tick-marked equal sides, and a page of geometric figures with lettered labels. A designer could take their clean, hand-labelled construction-drawing style and the simple geometric forms for diagrams, logos, or pattern layouts.
