Wedge-marks in clay.
Cuneiform tablets are clay with wedge-shaped impressions made by a reed stylus. Shape and script style indicate period and language — the script served Sumerian, Akkadian, and their neighbours across three thousand years.
Most tablets are administrative — rations, receipts, contracts — and a pillow-shaped tablet that fits the palm is the classic form. Cones, bricks, and cylinders with royal inscriptions are building dedications; cylinder seals, rolled across wet clay, belong to the same world.
Firing may be accidental (a burnt archive) or deliberate. Unbaked tablets are simply dried mud and crumble at a touch — handle with great care and keep them dry.
Provenance carries real ethical weight here: unprovenanced tablets have fuelled looting in Iraq and Syria, and several countries bar their trade. Record documented history plainly, and treat its absence as the serious gap it is.
