Where 570 fits
Why 570 is special
It may be derived from animal or plant sources and the label does not say which, which is the same ambiguity that affects E471.

Read as powers of two: 512 + 32 + 16 + 8 + 2 = 570.
In historical numeral systems
Egyptian
5 coils of rope, 7 hobbles
5 × 100 + 7 × 10 = 570. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
9 vertical wedges (sixties place), 3 corner wedges (units place)
9 × 60 + 30 = 570. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
phi, then omicron, marked as a numeral
phi-omicron + keraia
phi + omicron written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then qof, then ayin
tav-qof-ayin
tav (400) + qof (100) + ayin (70) = 570, written in descending order.
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.
