For this purpose he visited the Levant and Egypt. When in Egypt he measured the pyramids, and, finding that the angles formed by the sides of the largest were in the direction of the four cardinal points, he concluded that this position must have been intended, and also that the poles of the earth and meridians had not deviated since the erection of those structures. He was made a member of the French Academy of Sciences in 1695, and died in Paris on 16 January 1710. The botanist and explorer Louis Feuillée was one of his pupils.
