In the 19th century geometry was often taught using solid models. This dissected cone is from St Petersburg and was presented by the Pedagogical Museum to the 1876 Special Loan Exhibition, where educational and scientific instruments from around the developed world were displayed. It is cut to show a parabola, hyperbola, ellipse and triangle. Elementary geometry teaching was based on the works of the Ancient Greeks; the definitive book on conics was that of Apollonius, written c. 200 BC.
