Description
These are diagrams originally used by Thomas Hobbes for his proofs for squaring the circle and doubling the cube. Christian Huygens's criticisms of these proofs were read at the meeting of the Royal Society on 31 December 1662.

Object history
At the meeting of the Royal Society on 24 December 1662, ‘Dr. Pope was desired to make the diagram in the great relating to Monsieur Huygens’s Latin letter to Sir Robert Moray, in answer to Mr. Hobbes’s defence of his geometrical problems’ (Birch 1:166). This is probably the enlarged version made by Pope.
31 December 1662, ‘Monsieur Huygens’s letter to Sir Robert Moray was read, containing his answer to Mr. Hobbes’s defence of certain geometrical problems about the duplication of the cube, etc. And it was ordered to be sent to Mr. Hobbes by the means of the stationer appointed by himself to receive the judgments of foreign mathematicians concerning that matter’ (Birch 1:167).
