Topic: Matthias Quadt

The discussion focuses on 16th and 17th-century cartography, specifically the work of Matthias Quadt and Gerhardus Mercator. Hubbard explains that these maps often depicted four large islands at the North Pole, a feature also found on the 1507 Johannes Ruysch map used by Christopher Columbus. Hubbard argues that Columbus was searching for missing landmasses rather than a route to a flat earth's edge.

The conversation shifts to Friesland, a "phantom island" that appeared on maps by Cornelius Wyfliet and Matthias Quadt with detailed city names before disappearing. Hubbard suggests the island may have sunk, noting that soundings in the North Sea revealed shallow areas only 200 feet deep. He also discusses the depiction of extinct sea creatures on these maps, which he believes were real animals wiped out by early industrial sailors.
