Mens Artificialis
Camillo's 1530s phrase for an externalized cognitive architecture — the direct linguistic and conceptual ancestor of artificial intelligence, coined four centuries before Dartmouth.

Camillo genuinely believed he was constructing, in wood and paint, a cognitive architecture capable of providing any visitor with capabilities that individual human memory could not achieve. The phrase deserves to sit in the air. Five centuries before the 1956 Dartmouth workshop formally named artificial intelligence as a research field, a Renaissance professor was explicitly constructing what he called an artificial mind. The conceptual continuity between Camillo's aspiration and contemporary AI is not analogy. It is genealogy. The tools have changed. The ambition — total knowledge organized in navigable external structure — has not.

The Latin mens artificialis ("artificial mind") and the related mens fenestrata ("windowed mind") framed the theater
