Abstract

**Focused Discovery: Nippur Scribal Curriculum and the Sexagesimal Geometric Kernel** The Nippur scribal school corpus (House F, Level III, ca. 1740 BCE) reveals a standardized curriculum — *List A* (metrological lists), *List B* (multiplication tables), and *List C* (reciprocal tables) — culminating in advanced problem texts. Tablet **N3914** (CDLI P230345), a Type IV lenticular "hand-tablet," preserves a complete reciprocal table (standard *igi*-table) for integers 1–81, explicitly calculating sexagesimal reciprocals such as `igi 7 = 8;34,17,8,34,17` (repeating) and `igi 1,21 = 44,26,40`. This demonstrates algorithmic long division in base-60, not mere lookup. Geometric sophistication appears in **IM 58045** (Nippur, Old Babylonian), a round tablet depicting a circle inscribed with a 3-4-5 triangle and its perpendicular bisectors. The scribe calculates the diagonal of a unit square via the coefficient list value `1;24,51,10` (YBC 7289 value), yielding √2 ≈ 1.41421296 — accurate to Author: Andrew Stewart Caldin, Independent Researcher, UK.
