Second edition in Latin and an influential book on the Continent. Newton published this edition in Latin to reach the Continental audience which had been little influenced by his optical experiments. The edition served its purpose and caused numerous demonstrations of his theory of colors to be performed in Paris. Newton’s optical theories began to spread significantly outside Great Britain as a result of this book. See Westfall’s Never at Rest, pp. 794-95.
