notes: label: Description
content: This is one of four string models showing space curves of fourth order that were designed by the German mathematician Hermann Wiener (1857-1939) and first published by Ludwig Brill in 1884. The model has a metal frame painted black. The top and bottom are both in the shape of a hollowed X, with a small circle at the center. The four sides have oval shapes, with two opposite sides having differently shaped ovals than the other two. A few curved wires join adjacent sides and have beads running on them. In more complete versions of the model, strings join opposite ovals to form cylinders and also run between other metal bars. This example has no maker's tag.
