Finally he and his father and uncle desired to return to Venice. They had all served Kublai Khan faithfully and he had appreciated it and given them rich rewards; but he did not wish to let them go. While the matter was being talked over an embassy arrived in Peking from the king of Persia. This monarch desired to marry the daughter of Kublai Khan, the Princess Cocachin, and he had sent to ask her father for her hand. Consent was given, and Kublai Khan fitted out a fleet of fourteen ships to carry the wedding party to Persia. The Princess Cocachin was a great friend of Marco Polo, and urged her father to allow him to go with the party. Finally Kublai Khan gave his consent. Marco's father and uncle were also allowed to go, and the three Venetians left China. [Illustration: VENETIAN SHIPS] The fleet with the wedding party on board sailed southward on the China Sea. It was a long and perilous voyage. Stops were made at Borneo, Sumatra, Ceylon and other places, until the ships entered the Persian Gulf and the princess was safely landed. After they reached the capital of Persia the party, including the three Venetians, was entertained by the Persians for weeks in a magnificent manner and costly presents were given to all. At last the Venetians left their friends, went to the Black Sea and took ship for Venice. They had been away so long and were so much changed in appearance that none of their relations and old friends knew them when they arrived in Venice. As they were dressed in Tatar costume and sometimes spoke the Chinese language to one another, they found it hard to convince people that they were members of the Polo family. At length, on order to show that they were the men that they declared themselves to be, they gave a dinner to all their relations and old friends. When the guests arrived they were greeted by the travelers, arrayed in gorgeous Chinese robes of crimson satin. After the first course they appeared in crimson damask; after the second, they changed their costumes to crimson velvet; while at the end of the dinner they appeared in the usual garb of wealthy Venetians. "Now, my friends," said Marco, "I will show you something that will please you." He then brought into the room the rough Tatar coats which he and his father and uncle had worn when they reached Venice. Cutting open the seams, he took from inside the lining packets filled with rubies, emeralds and diamonds. It was the finest collection of jewels ever seen in Venice. The guests were now persuaded that their hosts were indeed what they claimed to be. II
