Description
Both Renatus Slusius and Christian Huygens were interested in 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 (the Latinised name of Ibn al-Haytham (965-1045)). The diagrams, relating to this problem, are from Slusius’s letter to Oldenburg (EL/S1/66/003-04), in which he claimed that Huygens’s construction was the same as his. This letter was published by Oldenburg in Philosophical Transactions of the Royal Society, vol. 8, no. 97 (October 1673), pp. 6119-22, together with a letter from Huygens.
These diagrams are copied at LBC/4/176-77.
