Seventeen voyages pushed Europe's mapped world from the Mediterranean to every ocean in under 400 years

Asked:“Create a chronological world map that shows how European geographic knowledge expanded during the Age of Exploration, from approximately 1400 to 1800… Animate major voyages in chronological order as colored routes… Add a playable and draggable timeline…” — with the follow-up: “плеер не включается. Просто черный экран. Кнопки не жмутся.” This is the rebuilt, reliability-first player.

17 expeditions, 127 generalized route waypoints and 17 fog-lifting reveal events, 1487–1795, drawn over a baseline of what European cartographers reliably held around 1400: Europe, the Mediterranean and Black Sea, and the Atlantic coast down to Cape Bojador. The dark layer is European cartographic ignorance only — every "revealed" coast was already inhabited and known to its own peoples.

Method: 17 expeditions rebuilt from 127 generalized modern-coordinate waypoints (not reconstructed daily ship tracks; uncertain landfalls are labeled in the data) plus 17 voyage-driven reveal events and one c.1400 baseline description. The fog layer shows European cartographic awareness only, never first human knowledge or settlement — every region shown as "revealed" was already inhabited. Playback compresses empty years (~40 historical years per second in Exhibit mode) and slows for voyages; reveals are approximate buffered corridors around routes, not surveyed polygons. Route colors come from the source data per explorer/sponsor. Some route detail is simplified for space.
