The Map That Named America
In 1507, in a small printing town in the Vosges mountains, a mapmaker and a poet gave two continents their name — a name born of a mistake, honoring the wrong man. This page publishes every source behind the episode, and the provenance of every archival image on screen.
Adversarial fact-check completed July 15, 2026, before voiceover. Every contestable date, number, name, attribution, and superlative was independently verified against two or more reputable sources, with the Library of Congress — holder of the sole surviving copy of the 1507 map — as the gold source. 26 claims verified. The gate produced one correction (the object of Josef Fischer's 1901 search) and one precision hedge (the population figure in the cold open), both applied to the narration before recording. One genuinely-unsettled date — Waldseemüller's death year, which authorities place anywhere from 1518 to 1522 — is delivered with an explicit “around” hedge.

PD basis key: US-Gov — digitized and published by a United States federal institution; Age — the underlying work was published before 1930 and its author has been dead more than 70 years, placing it in the public domain worldwide by term expiry; 2-D repro — a faithful photographic reproduction of a two-dimensional public-domain work gains no new copyright (Bridgeman Art Library v. Corel Corp., 36 F. Supp. 2d 191, S.D.N.Y. 1999), so the scan inherits the original's public-domain status; CC0 — the holding institution additionally released the file under a CC0 public-domain dedication.
