ouerthwart equally distant one from an other will make sixeteene
quadrats, then adde to the figure halfe as much more in like proportion,
diuiding the adiunct you shall finde foure and twenty squares. This
figure shall serue of credycels to make the inlepturgie and briefe

drawing lines from one to another, and they wil make the Rhombas.
