Read the full account
Wellcome MS Arabic 155 is a complete Canon transcribed at Isfahan in 1632 and now a public-domain work page with images. The dated object is the 1632 copy; the public carrier is the Wellcome Collection record. Avicenna did not copy Isfahan. A complete Arabic witness in a public library is an access path.
Context
The row stores the readable complete copy.
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 public complete Arabic Canon is a scholarly access path, not a 1025 autograph.
