- Description
- Cutting a cone by a plane yields several different curves of second degree, which are known as conic sections. This white plaster model of a circular cone has two parts. One is fixed to the base. A second and the largest is cut by a plane on one side to give a hyperbola and on the other side to give an ellipse. Two further pieces are missing. A paper tag on the front of the base reads: 15. A second, partial tag reads: Kreiskeg.... ebenen schitten. (/) Verl. v. L. Brill. 6. Ser. Nr. 5.
