Summary of “How to Put a Fake Island on the Map”

Zeno called the island Frisland and claimed that two of his ancestors, Antonio and his brother Nicolò, had discovered the island in the 1380s.
Zeno’s map provided additional support for his story.
In his book, Zeno claimed the map dated back to the 1390s, but its sources are clearly from the 16th century.
Bordone’s Isolario of 1528 not only provided images of North Atlantic islands, but it also contained descriptions of Vespucci’s voyage and the island of Hispaniola, which served as a template for Zeno’s picture of the New World inhabitants.
Even the map can’t fully explain the enduring power of Zeno’s story.
To understand why modern scholars might defend Zeno’s story, look at another case of alleged exploration forgery: the Vinland map.
Many scholars argue that the Vinland map is a forgery, perhaps because it lacks a compelling element found in the Zeno tale-a centuries-long track record of evidence.
Zeno’s map gave the appearance of truth to his claims, but the English declaration of ownership over Frisland in 1580 reveals the true power of Zeno’s story.
