Opticks: or, a Treatise of the Reflexions, Refractions, Inflexions and Colours of Light

London 1704 in English is the true first and there is no earlier foreign-language edition — this is one of the rare cases where the English book is the original. The trap runs the other way: the Latin Optice (London: Smith & Walford, 1706), translated by Samuel Clarke, is a first thus, not a first edition, and is mistaken for the 'real' first because period science was expected in Latin. It is also textually different, expanding the Queries from 16 to 23. The second English edition (W. and J. Innys, 1717/18) prints Newton's name, expands the Queries to 31, drops the two Latin treatises, and was reset in a smaller format with newly engraved plates.
