My name is fit for rappers, though my title is a count;
The time I spent at sea no man of my day could surmount.
An empire's expansion was in large part my account;
The spice trade bought in riches in extremely large amounts.
My journeys brought me gold and international acclaim;
Around the cape and all the way back was my route to fame.
I am not a Basque man, nor a player of a game,
Though you might believe so on the basis of my name.
Who am I?
