A 1569 Antwerp printing from the Plantin press by Cornelius Gemma, a Louvain medical professor, setting out a circular method of classification for medicine, philosophy and the sciences for scholarly readers. Its pictures are dense printed tables and concentric diagrams of rings, sectors and labels, showing how a designer might build a radial or tabular information layout from such schematic structure.
