Isaac Newton (1643-1727).

Mathematical Principles of Natural Philosophy. London: for W. Strahan and T. Cadell, 1777.

First edition of Robert Thorp's translation of the Principia, uncut and in the original boards. This is the first edition of the second translation into English of the Principia, although only the first volume was published. Thorp's translation, 'though based on Motte's edition of 1729, is considered by Cohen (Newton, 1969, p.iv) to be "notably improved and amended." Further, he declared, for anyone wishing to follow Newton's reasoning and "to comprehend this great treatise on its own terms, there is no better work available in English".' (Gjertsen, The Newton Handbook). The present lot is quite rare; only 7 complete copies have sold at auction in the past 40 years (ABPC/RBH). A second edition followed in 1802. Thorp was one of the three editors of the Excerpta published in 1765. Wallis 28. Not in Babson

Volume 1, all published, quarto (300 x 236mm). Half-title, 6pp. of subscribers, 22 folding engraved plates (leaves Kk2-3 coming loose, tiny marginal hole to d4, occasional light scattered spotting and browning). Original boards, uncut (rebacked with paper backstrip, short splits to joints but holding, covers lightly soiled with brown spot to upper cover going through to half-title and title, extremities rubbed, corners bumped).
