Where 146 fits
Why 146 is special
Two of the Mediterranean's great cities were levelled in the same year by the same power. The claim that Rome sowed the ground with salt appears in no ancient source and is a nineteenth-century invention.

CXLVI uses the subtractive pair XL: ten before fifty — fifty minus ten.

Read as powers of two: 128 + 16 + 2 = 146.
In historical numeral systems
Egyptian
1 coil of rope, 4 hobbles, 6 strokes
1 × 100 + 4 × 10 + 6 × 1 = 146. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 vertical wedges (sixties place), 2 corner wedges + 6 vertical wedges (units place)
2 × 60 + 26 = 146. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
rho, then mu, then stigma, marked as a numeral
rho-mu-stigma + keraia
rho + mu + stigma written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
qof, then mem, then vav
qof-mem-vav
qof (100) + mem (40) + vav (6) = 146, written in descending order.
Maya
1 bar + 2 dots (upper, twenties place) over 1 bar + 1 dot (lower, units place)
7 × 20 + 6 = 146. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.

Rome destroyed Carthage in 146 BC, roughly six centuries after its own traditional founding. The claim that it salted the ground appears in no ancient source and dates from the nineteenth century.
