Cuneiform Numeric Sign Four Ash Tenu

It marks four within a context-bound slanted numeral series. In scholarly transliteration, 4(AŠ@t), AŠ names the ash series and @t marks the slanted tenû form. “Four” gives its place in the series; the measuring system tells readers what quantity it represents. It is a historical measurement sign, not a free-standing modern 4.

Its recognizable series is documented in Mesopotamia’s Early Dynastic period, around 2900–2335 BCE. Different metrological systems let scribes record goods, land area, volume, and other administrative quantities with number series suited to each measure. The slanted-numeral group also appears in Ur III dates (the Third Dynasty of Ur) and subtractive notation, where written values involve subtraction.

Why is it not just the number 4?

Cuneiform numeral values depend on the measuring system. Mesopotamian scribes used different numeral series for different kinds of quantity, so a sign’s value was not always one universal modern number. Scholarly sign lists use forms such as 4(aš@t), 4(diš@t), and 4(iku@t) for this sign in different metrological series.

That makes it related to, but not interchangeable with, 𒐂 Cuneiform Numeric Sign Four Ash or 𒐉 Cuneiform Numeric Sign Four Dish. The first is the upright ash-series counterpart; the second belongs to a parallel dish series. 𒑌 is the slanted ash tenû form, with its slant encoded in the character rather than added by a font.

Why can fonts draw it differently?

Fonts can use different period styles—or lack this glyph. Cuneiform fonts may be designed for different historical periods, so the same encoded sign can look different across typefaces. That changes its appearance, not its identity.

If 𒑌 appears as an empty box, the selected font lacks its glyph. That is missing font coverage, not a change in the character or proof that a neighboring four-sign is the same.
