Squares & Triangles
Set Squares

A few squares and triangles from the Mathematics collection in the Medicine and Science.

Many of the set squares in the mathematics collection are early modern treasures handcrafted in Europe. A particularly interesting example has a then-new metric scale. (See also the scale rules group for information on the history of length measures.) Also included on this page are sets of drawing instruments that contain set squares and artillery squares, used to design fortifications and position artillery.
