Where 1818 fits
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.
Same number, different meanings

In 1818, Mary Shelley's Frankenstein was published (England).

Frankenstein's creature reads Milton and argues its case at length. Film adaptations almost universally make it mute, which removes the moral argument the novel is built around.

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.
