I want to know the answer to the following question:
What was the name of the Portuguese explorer?
All the background I'm provided with is that "Early reports of Europeans reaching this area include those of the Venetian Alvise Cadamosto's voyage of 1455, the 1479–1480 voyage by Flemish-French trader Eustache de la Fosse, and Diogo Cão.". Is that enough to answer the question?
Answer: yes
