Read the full account
ISTC and the incunable tradition date a complete Latin Canon medicinae at Milan, 12 February 1473, in Gerard of Cremona’s version. Avicenna did not operate a press. Type made a five-book medical encyclopedia copyable in Latin faculties.
Context
Print also froze humoral lock-in. Split that harm. High confidence on the bibliographic date cluster, with the known rivalry between Milan and Strasbourg issues stated rather than hidden.
Avicenna is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
A 1473 Latin Canon in type is a knowledge-access ignition, not a clinic roster.
