Money did not begin as a coin you could bite. Long before the first struck metal, Mesopotamia ran on credit: what you owed the temple, the palace, the merchant — reckoned in weighed silver and barley, pressed into clay. Interest-bearing debt is attested in cuneiform from the third millennium BCE, roughly 1,700 years before the first coin. That interest had a name — máš — and a rate, and, when it crushed too many people, a way to be cancelled: a royal decree of ama-gi, "return to the mother."
AGORA anchors on Enheduanna (c. 2300 BCE, en-priestess of Nanna at Ur, daughter of Sargon) by era only — she was a priestess and the earliest named author-figure, never a moneylender, accountant, or debt-reformer. The tie is purely chronological: her lifetime dates the sphere, and the world she lived in already ran on interest-bearing clay debt. The honest placement, kept exact: the ama-gi debt-release decrees come from Lagash just before her (Enmetena c. 2400, Urukagina c. 2350 BCE); the famous Babylonian "clean slate" edicts (Hammurabi, Ammi-saduqa) are 500–700 years after her. Her own works survive only in Old-Babylonian copies ~500 years later and her authorship is debated — one reading even takes "Enheduanna" as the name of the office, not the person. She is a dating anchor, not a preserved source.
You borrow, and the debt grows on its own. The Sumerian word for that growth, máš, also meant "young goat" — money that gives birth, the same image as Greek tokos (offspring) and Latin faenus. Let the years pass and watch it compound at the standard rate. Then, when it has outgrown any hope of repayment, issue the decree.
Real rates, computed live. ~20%/yr on silver (=1/5, the "1/60 per month" that was stable for over a millennium) and ~33⅓%/yr on barley (=1/3) are the standard norms, also written as legal ceilings in the Laws of Eshnunna and the Code of Hammurabi — not a single universal statute (real contracts vary; some silver ran ~25%, some loans were interest-free; grain ceilings drifted down over the centuries). The "goat" in máš is a shared metaphor, not a mechanism: Michael Hudson reads it as a "baby fraction" born each period (1/60 a month), calendrical arithmetic, not literal herds breeding. The clean slate is a real institution — Sumerian amargi / Akkadian andurarum ("release") / misharum ("equity") — but a royal tool placed in its true time: amargi at Lagash c. 2400 BCE, the Babylonian misharum edicts c. 1750 BCE, not an Enheduanna-era Ur institution.
𒂼𒄄 · ama-gi = ama ("mother") + gi/gi₄ ("return, restore") → literally "return to the mother." In economic-legal use it meant release from debt, from debt-bondage, from obligation — a restoration to one's prior free status. By the Ur III period it was the standard word for manumission.
The Assyriologist Samuel Noah Kramer called ama-gi "the earliest known written reference to the concept of freedom" — but he meant freedom from debt-bondage, not political liberty, and he added, honestly, that "we still do not know why this figure of speech came to be used for freedom." Modern scholars (Diakonoff) read it as restoration to the original condition. So: attribute the "first word for freedom" line to Kramer as his careful claim — not a settled fact, and not the modern "amagi = liberty" banner, which over-reads it.

Where it belongs: the-ledger (the record it's written on) · the-shekel (the unit it's counted in) · debasement · money.
AVAN's inverse companion: 負い目 · Oime — the felt debt no ledger holds and no decree clears; where a clay tablet can be zeroed and an ama-gi decree can cancel the record, the obligation that was never written down survives every clean slate.
