Object Details
- Description
- This brass circular protractor is divided by single degrees and marked every thirty degrees in the clockwise direction with Japanese characters facing outwards and representing the Chinese zodiac: mouse, cow, tiger, rabbit, dragon, snake, horse, sheep, monkey, chicken, dog, and boar. Four arms extend toward the center of the protractor and meet around an open circle 3 cm. in diameter. The circle is open, except for a protrusion containing a pinhole at the origin point.
- The Japanese Empire Department of Education assembled an extensive exhibit of books, reports, examinations, maps, photographs, paintings, classroom equipment, medical apparatus, and drawing instruments for the 1876 World's Fair, the Centennial Exposition in Philadelphia. Five types of protractors were included in the display, two of which survive in the Smithsonian's National Museum of American History.
