Oannes

← Encyclopedia

Oannes is the name given by the Babylonian priest Berossus to a creature, part fish and part man, who rose from the sea to teach the first inhabitants of Mesopotamia the whole of civilized life. The figure is known almost entirely from a single account, transmitted at several removes, yet it preserves one of the oldest surviving images of how the arts of culture were thought to have come to humankind — not invented over time, but delivered whole, from outside.

The source is the Babyloniaca, a history of Babylon that Berossus, a priest of Bel-Marduk, wrote in Greek in the early third century BCE, dedicating it to the Seleucid king Antiochus I. The work itself is lost; what remains are quotations preserved by later writers — Alexander Polyhistor, Apollodorus, Abydenus — and copied in turn by the Christian chroniclers Eusebius and George Syncellus, so that the text now reaches us only as a quotation inside a quotation. According to it, in the first year of the world a being called Oannes emerged from the Erythraean Sea, the body of a fish but bearing beneath the fish’s head another, human head, and feet like a man’s. It passed the day among people, taking no food, and taught them letters and the sciences, the building of cities and temples, the founding of laws, geometry, the working of the land, and the gathering of seeds and fruits — in short, everything that softens a human life. At sunset it returned to the sea. Berossus reports that nothing was discovered afterward; later sages who appeared were only repeating what Oannes had first disclosed.

In the older Mesopotamian material that scholarship has since recovered, the figure stands among the apkallu, the seven sages held to have lived before the Flood and to have brought the orders of civilization to the cities of Sumer. The Greek “Oannes” is generally traced to the Sumerian Uanna or Uan, the first of these sages, attached to Eridu — the name surfacing in the same orbit as Adapa, the primordial wise man of Babylonian myth, with whom Oannes is frequently linked though the exact relation between the figures is debated.

The motif of culture brought by a being from elsewhere recurs widely: the Etruscan Tages rising from a furrow to teach divination, the Egyptian Agathodaemon as revealer of wisdom. The parallels are real, and they point to a shared instinct about where knowledge comes from rather than to any single borrowed story. What the Babylonian version keeps, more starkly than most, is the strangeness of the messenger — that the foundations of human order were imagined as the gift of something that did not belong to the land at all, and went back each night to the water.
