Napier's Judgment Window
Logarithm Inventor Napier Put God's Judgment Between 1688 and 1700. Both Years Filed Other News
Proposition 14 of A Plaine Discovery (1593): the day of God's judgment appears to fall betwixt those years. Neither obliged.
What was said
“The day of Gods judgement appears to fall betwixt the yeares of Christ, 1688. and 1700.”
— John Napier of Merchiston (Scottish mathematician; A Plaine Discovery of the Whole Revelation) · said 1593 · due 1688–1700
1688 brought the Glorious Revolution; 1700 brought a new century. Neither brought Napier's day of judgment.
The Story
Before he shortened multiplication, John Napier shortened the Christian calendar.
In A Plaine Discovery of the Whole Revelation (1593) he numbered seals, trumpets, and jubilees until Proposition 14: the day of God's judgment appears to fall betwixt the years of Christ 1688 and 1700.
1688 toppled a king in England. 1700 rolled into a new century. Judgment Day stayed off the register. Napier's logarithms outlived his timetable.
