What does Michele de Cuneo tell us in his writing about Columbus' purpose?

From the text:

The sources are perfectly clear about Columbus’s motivation: in 1495, for instance, Michele de Cuneo wrote about accompanying Columbus on his 1494 expedition into the interior of Haiti: “After we had rested for several days in our settlement, it seemed to the Lord Admiral that it was time to put into execution his desire to search for gold, which was the main reason he had started on so great a voyage full of so many dangers.”
