Object Details
- Description
- A wooden bar (6-1/8" x 2" x 3/4") is attached to a flat wooden handle (17-7/8" x 2" x 1/8") by nine wooden pegs. By the 17th century, draftsmen used T-squares to help them draw horizontal lines. The instrument was also used in conjunction with a set square or triangle to draw vertical and diagonal lines. The dating of other objects from this donor suggests this object was made about 1900. Compare to MA.328397 and MA.328398.
