In the 1450s, Venetian explorer Alvise Cadamosto would conduct two voyages of exploration for Prince Henry the Navigator. These voyages are a representation of the many expeditions dispatched by Henry in his lifetime. On these journeys, Cadamosto would discover the Cape Verde Islands, and expand the map of the west African coast as known to Europe.
This is a single episode series
There are not a lot of resources on Cadamosto. However, we do have his book, Navigazioni. The book is actually pretty hard to find in print for a reasonable price, but you can find links to it online – which I have provided below.
