Gnomonice is a 1562 Latin treatise on sundial design by the Nuremberg mathematician Andreas Schöner, published in Nuremberg by Johannes Montanus and Ulrich Neuber for scholars and instrument makers. Its pictures are dense geometric diagrams of sun-ray projections, arcs, and hour lines drawn with fine black strokes on plain paper, showing how a designer can build radiating, grid-based linework from precise construction geometry.
