Description
The debate between Huygens and Slusius about the solution to the problem of finding a point of reflection on the surface of a spherical mirror in relation to two points, the eye and the visible object, attributed to Alhazen (Ibn al-Haytham (965-1045)) had been discussed at the meetings of the Royal Society on 3 July 1672 and 18 December 1672.
This diagram is from Slusius's discussion of Alhazen's problem in a letter to Oldenburg, which was printed in Philosophical Transactions of the Royal Society, vol. 8, no. 98 (November 1673), pp. 6145-46.
The diagram in the letter is at EL/S1/72/003. There is another copy at LBC/5/371.
