This study investigates how ancient scholars from mid-first millennium Babylonia and Assyria advertised their possession of secret knowledge to scribal students in order to bolster and perpetuate scholarly social prestige and power in society. After a brief theoretical orientation to issues surrounding the study of secrecy and a sketch of the two-tier scribal educational model developed by Petra Gesche, the study presents evidence for advertising scholarly secrets from the circumstances surrounding the storage and handling of tablets bearing the Geheimwissen colophon and from two literary texts copied by first-tier scribes, “In Praise of the Scribal Art” and “The Standard Babylonian Gilgamesh Epic.”
