Why 1740 is special

It started because a woman inherited the Habsburg lands and several powers had guaranteed her succession and then ignored their guarantees. Treaty obligations proved worth less than opportunity.

In historical numeral systems

Egyptian

1 lotus, 7 coils of rope, 4 hobbles

1 × 1,000 + 7 × 100 + 4 × 10 = 1,740. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

2 corner wedges + 9 vertical wedges (sixties place), empty units place

29 × 60 + 0 = 1740. Places are separated by a space on the tablet, with the higher place written first. The second place is empty, and this is precisely the case the early system could not write unambiguously — the same wedges alone would also read as 1.

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.
