Why 1588 is special

Weather did much of the work — the fleet was scattered by storms after being harried in the Channel — and England's own counter-armada the following year failed just as badly. The victory's outsized place in English national memory is itself a historical subject.

In historical numeral systems

Egyptian

1 lotus, 5 coils of rope, 8 hobbles, 8 strokes

1 × 1,000 + 5 × 100 + 8 × 10 + 8 × 1 = 1,588. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

2 corner wedges + 6 vertical wedges (sixties place), 2 corner wedges + 8 vertical wedges (units place)

26 × 60 + 28 = 1588. 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.

  • The Spanish Armada was harried in the Channel and then scattered by storms on the route home. England's own armada against Spain the following year failed at least as badly, and its near-absence from popular memory alongside 1588's prominence is itself a subject historians write about.
