notes: label: Description
content: In 1880, Ernst Lange, a student at the mathematical institute of the technical high school in Munich, working under the direction of Felix Klein, designed four plaster models of space curves of degree three drawn on cylinders with cross sections that were conic sections. All of these curves represented the intersection of a surface of degree two with the cylinder shown.
label: Description
content: This model, the second in the series, shows the intersection of two hyperbolic cylinders, on the surface of a hyperbolic cylinder. The curve of intersection, called a cubic hyperbola, is incised on the model.
