De cometis dissertatio astronomico-physica
A 1624 astronomical treatise on comets, printed in Venice by the Varisciana press and written by Giovanni Camillo Glorioso, a 17th-century Italian scholar, for learned readers of early modern astronomy. Its pictures are plain black-line geometric diagrams of quadrants, arcs and lettered points with dotted sight lines, offering a designer clean, schematic line work and a model for labelled technical drawing.
