    Description
    Diagram in Robert Hooke's paper on the inflection of a direct motion into a curve by a supervening attractive principle. Hooke sought to explain why planets moved in curved or elliptical orbits. One of his hypotheses was that the curved motion came from the attractive property of a body at the centre. In this paper, Hooke attempts to explain this hypothesis through a series of experiments using a pendulum. It was read at a meeting of the Royal Society on 23 May 1666.

    This image is from a partial copy of the Register Book now among the Boyle papers. It is copied from the image at RBO/3/115. Other versions can be found at Cl.P/20/41/007 and RBC/2/244.

    At the meeting of the Royal Society on 23 May 1666, ‘A paper of Mr. Hooke concerning the inflection of a direct motion into a curve by a supervening attractive principle was read, and order’d to be registered’ (Birch 2:90). The text and reference to the figure, but not the figure itself, are printed in Birch 2:91-92.
