Why 1692 is special

Twenty people were executed over several months on spectral evidence — testimony about dreams and visions that could not be tested. The colony later issued reversals and compensation, and the episode became the standard reference for judicial panic.

In historical numeral systems

Egyptian

1 lotus, 6 coils of rope, 9 hobbles, 2 strokes

1 × 1,000 + 6 × 100 + 9 × 10 + 2 × 1 = 1,692. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

2 corner wedges + 8 vertical wedges (sixties place), 1 corner wedge + 2 vertical wedges (units place)

28 × 60 + 12 = 1692. Places are separated by a space on the tablet, with the higher place written first.

Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Law & regulation

  • Salem's convictions rested largely on spectral evidence: claims about what a defendant's spirit had done, which no defence could rebut. Excluding that category of testimony ended the trials almost immediately, which is the clearest possible statement of what had been wrong.
