birch bark scrolls

The Ojibwa (Anishinaabe) people of North America had written down complex geometrical patterns and shapes on birch bark scrolls, known as wiigwaasabak in the Ojibwe language. These writings enabled one to memorize complex ideas, and to pass along history and stories to the next generations. Several such scrolls are in museums including one on display at the Smithsonian Museum in Washington, DC. One recent study of a few scrolls details the complex math and memorizing scheme associated with the symbols that were used long ago. The complex writings also included astronomy, mapping, family lineage, songs, and migration routes. In addition to birch bark, copper may have also been used, along with hides, pottery, and other artifacts.
