Description
A diagram originally used by Descartes to determine the limits of the primary and secondary rainbows in angular measure from the observer's eyes. In his letter to Henry Oldenburg dated 20 August 1670, Franciscus Renatus Slusius suggested that he could find the solution by experimenting on a glass globe full of water. Slusius asked Oldenburg to transmit this solution to Isaac Barrow, who was doubtful of its accuracy.
