draft revisions to three sections of the first edition of the Philosophiae naturalis principia mathematica,
a heavily corrected draft with three additional notes by the Scottish mathematician
and astronomer David Gregory. (£600,000–900,000)
Isaac Newton’s (1642-1727) handwritten revisions to the Principia, arguably the most important single work in the history of science, will come up at Christie’s in London on July 8. The estimate for the work, which will feature at the Exceptional Sale, is £600,000–900,000. This is an unpublished, working manuscript for Newton’s projected and ultimately abandoned second edition, and includes additional notes by the Scottish mathematician and astronomer David Gregory (1659-1708). The manuscript was in the archive of Gregory until the 1860’s, and was most recently in the notable collection of Maurice Car. UPDATE: THIS MADE £1,702,500
