Why 1494 is special

The Treaty of Tordesillas drew a line down the Atlantic and assigned everything west to Spain and east to Portugal. Neither had seen most of the territory, no other power recognised it, and it is why Brazil speaks Portuguese while the rest of South America speaks Spanish.

1 × 1,000 + 4 × 100 + 9 × 10 + 4 × 1 = 1,494. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

2 corner wedges + 4 vertical wedges (sixties place), 5 corner wedges + 4 vertical wedges (units place)

24 × 60 + 54 = 1494. 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.
