Sir Isaac Newton's commentaries on the Book of Daniel and the Book of Revelation. Published in 1733.
Newton wrote an entire book interpreting the prophecies of the Biblical books of Daniel and the Revelation of John (also called "The Apocalypse"). His insights vary in several respects from the "standard" modern Christian interpretations, and his perspicacity might well be vindicated as the rest of these prophecies are yet fulfilled. Besides his immense intellect, he provides a huge contribution which few can supply even today. Newton had a wealth of knowledge of ancient history, obtained by reading mountains of documents in the original Greek, Latin and Hebrew, in which he saw many of those prophecies literally fulfilled long after they had been revealed. To him, it was a proof of the foreknowledge of God, which was his purpose in writing the book.
