Why 1860 is special
Huxley and Wilberforce argued publicly about Darwin's theory seven months after publication. The famous exchange about ancestry from apes is recorded only in accounts written decades later.

- History
In 1860, the Oxford evolution debate was held at the new University Museum, months after Darwin's Origin appeared (England).
- Science
The 1860 Oxford debate is remembered for a specific insult and reply, both recorded only in reminiscences written twenty to forty years afterwards. Contemporary reports describe a far less dramatic occasion.

In historical numeral systems
Egyptian
1 lotus, 8 coils of rope, 6 hobbles
1 × 1,000 + 8 × 100 + 6 × 10 = 1,860. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 1 vertical wedge (sixties place), empty units place
31 × 60 + 0 = 1860. 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.
