Why 1818 is special

It was written by a teenager, published anonymously, and is generally treated as the first science fiction novel because the creature is made by method rather than magic. The creature is also articulate and self-educated, which almost no adaptation preserves.

1818 connects to:

  • 1813 appears alongside
  • historical years appears in
  • 1816 developed from

In historical numeral systems

Egyptian

1 lotus, 8 coils of rope, 1 hobble, 8 strokes

1 × 1,000 + 8 × 100 + 1 × 10 + 8 × 1 = 1,818. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

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

30 × 60 + 18 = 1818. 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.
