But, during the next night, Bacchus, disguised as Mahomet, appears to the Moors in Calicut, and bids them inform the Zamorin that Da Gama is a pirate, whose rich goods he can secure if he will only follow their advice.
This suggestion, duly carried out, results in Da Gama's detention as a prisoner when he lands with his goods on the next day.

But, although the prime minister fancies the Portuguese fleet will soon be in his power, Da Gama has prudently given orders that, should any hostile demonstration occur before his return, his men are to man the guns and threaten to bombard the town.

When the Indian vessels therefore approach the Portuguese fleet, they are riddled with shot.
_Book IX._ Because the Portuguese next threaten to attack the town, the Zamorin promptly sends Da Gama back with a cargo of spices and gems and promises of fair treatment hereafter.

The Portuguese thereupon sail home, taking with them the faithful Moncaide, who is converted on the way and baptized as soon as they land at Lisbon.
Book X.On the homeward journey Venus, wishing to reward the brave Lusitanians for all their pains and indemnify them for their past hardships, leads them to her "Isle of Joy." Here she and her nymphs entertain them in the most acceptable mythological style, and a siren foretells in song all that will befall their native country between Vasco da Gama's journey and Camoens' time.

Venus herself guides the navigator to the top of a hill, whence she vouchsafes him a panoramic view of all the kingdoms of the earth and of the spheres which compose the universe.
In this canto we also have a synopsis of the life of St.Thomas, the Apostle of India, and see the Portuguese sail happily off with the beauteous brides they have won in Venus' Isle of Joy.
