First edition, first issue, of Newton’s fundamental experiments on the color spectrum. This classic work also explains such optical phenomena as the rainbow, "Newton’s rings," and the double refraction of the Icelandic spar. Newton opens his study with the claim, "My Design in this Book is not to explain the Properties of Light by Hypotheses, but to propose and prove them by Reason and Experiments." Because of Newton’s reliance on scientific method, Opticks remained for over a century “a work of great authority; 'supreme' in Andrade’s works 'as a record of experiment and scientific deduction from experiment'" (Printing and the Mind of Man).
Opticks was expanded from Newton's first publication (which was also the first major scientific discovery to be published in a scientific journal): "New Theory about Light and Colours," a paper that appeared in the Philosophical Transactions of the Royal Society in 1672. Opticks was by far the most popular of Newton's works during his lifetime; he supervised five editions himself (three in English and two in Latin), and two French editions were published before his death in 1727.
The two "Treatises of the Species and Magnitude of Curvilinear Figures" included at the end of the text are Newton’s first published mathematical papers and were intended to assert his priority over Leibniz in the discovery of the calculus.
This copy is the first issue, with the title printed in red and black within a border and with the imprint, but without the author's name; with page 120 in the second part misnumbered 112; and with the two treatises on calculus at the end of the work.
