Why 1772 is special

Somerset's case held that no positive law authorised slavery in England, so an enslaved man there could not be forcibly removed. It did not abolish slavery in the colonies, which is the distinction usually lost.

In historical numeral systems

Egyptian

1 lotus, 7 coils of rope, 7 hobbles, 2 strokes

1 × 1,000 + 7 × 100 + 7 × 10 + 2 × 1 = 1,772. 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), 3 corner wedges + 2 vertical wedges (units place)

29 × 60 + 32 = 1772. 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.
