Cuneiform Video: The Sumerian Tablet That Named the First 7 — And What Was Found Under Ur — E8 Intelligence Research

**Framing note:** The video title you quote does not correspond to a single, securely identified tablet in the published cuneiform record. "Named the first 7" is not a standard description applied to any known mathematical or astronomical tablet from Sumer or later Babylonia, and "what was found under Ur" is a documentary hook rather than a museum catalogue reference. So the honest answer is: I cannot tie that video to a specific BM, YBC, or Plimpton number, and any claim that it encodes φ, √2, or π should be treated as unsupported unless the presenter cites an actual excavation number and edition. What the real corpus does contain is more interesting than the mystery framing: - **YBC 7289** (Yale Babylonian Collection) is the famous √2 tablet: a square with diagonals, giving 1;24,51,10 in sexagesimal, which equals 1.41421296… — accurate to about six decimal places. No φ, no π. - **Plimpton 322** (Columbia, Plimpton 322) is a table of 15 rows of Pythagorean-like triples in base 60, o Author: Andrew Stewart Caldin, Independent Researcher, UK.
