Isaac Newton's 'Opticks: Or, A Treatise of the Reflexions, Refractions, Inflexions and Colours of Light' was originally published in Latin as 'Optice: sive, De Reflexionibus, Refractionibus, Inflexionibus et Coloribus Lucis, Libri Tres'. This work is Newton's study of the behavior of light and color, detailing his experiments with prisms and the color spectrum.
