Cuneiform writing was hard-won, mastered only through years in the 'tablet-house' (eduba), the scribal school. A small literate elite copied, memorized, and transmitted the whole stream of Mesopotamian knowledge — myth, hymn, law, omen, mathematics, and lexical lists. Sumerian school texts vividly depict student life: the discipline, the canings, the rivalry, the pride of the accomplished scribe. The scribal goddess was Nisaba (later the god Nabu); the scribe's exactness — copying 'according to its original' and naming the source-tablet — is the very habit of mind that preserved this civilization's ideas for us.
In short
The world of the cuneiform scribe (ṭupšarru) and the scribal school (Sumerian é-dub-ba-a, 'tablet-house'), where literacy, literature, and the learned tradition were transmitted under the patronage of Nisaba/Nabû.
Where it’s found
'The advice of a supervisor to a younger scribe' (E-dub-ba-a C, ETCSL 5.1.3, in corpus); 'A hymn to Nisaba' (Nisaba A, ETCSL 4.16.1, in corpus)
How the idea developed across Sumer, Babylon & Assyria
The Sumerian eduba texts (Old Babylonian) idealize a possibly already-archaic school; in the first millennium learning is organized around scholarly families and royal libraries (Ashurbanipal's at Nineveh) rather than the classic eduba. The patron shifts from Sumerian Nisaba to Babylonian Nabû.
