Read the full account

This catalog uses no Chinese autograph itinerary in Polo's hand. The public file is later European recension. Gazetteers mentioning similar routes are not his diary.

Context

Sharing later Chinese geography with Yuan and Ming compilers, not with Polo's pen, is required. Driver personal-data-protection is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

Why it matters

High confidence on the absence of an autograph diary here. The welfare reading on this path is worsening.

If a number is not in the two records named above, it is not supplied here.

What the sources establish

Britannica independently treats Il Milione as the main Polo source. Official carrier: Project Gutenberg — Travels as the public European file (https://www.gutenberg.org/ebooks/10636 (opens in a new tab); Project Gutenberg). Independent carrier: Britannica — sources for Polo (https://www.britannica.com/biography/Marco-Polo (opens in a new tab); Encyclopaedia Britannica).

Established: no autograph Chinese itinerary used here. Not established: that he wrote one now lost.

Confidence is stated on the impact path, not hidden in adjectives.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

That reading is an impact-path choice, not a property stored on the Fact itself.

Naming Marco Polo does not delete co-authors, institutions, or later transmitters. The lag from 1295-06-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
