content: This black wire model has a regular dodecahedron at its center and a lacework of wires going out, with numerous pentagons. The outside is a regular dodecahedron, with edges measuring 21.5 cm.
label: Description
content: In the late nineteenth century, several mathematicians thought of ways of envisioning four-dimensional surfaces in three-dimensional space. The German mathematician Victor Schlegel developed a series of wire and thread models for the purpose. The series was first published by Ludwig Brill in 1886.
label: Description
content: This model (presently misshapen and missing its threads) represents the 120-cell. It is the analog of a regular dodecahedron (which has twelve pentagons as faces, three around each vertex). The 120-cell is built up of 120 dodecahedra, three around each edge.
label: Description
content: This example of the model was exhibited at the Columbian Exposition, a World’s Fair held in Chicago in 1893.
