The text reads:

"Pizarro returned to Spain in 1528 and appealed to the king to grant him permission to conquer Peru. With him, he brought gold and silver as evidence of its potential wealth. On 26 July 1529, a royal agreement was signed in which Pizarro was made governor of all the territory, up to 200 leagues South of Guayaquil. Almagro was made commander of Tumbes, while the priest, de Luque, was made Bishop of Tumbez." This engraving shows Pizarro appealing to the dignitaries in the royal court and symbolically, in the background, the gold that was plundered is shown being loaded aboard a ship.
