But in reality it was only partially accomplished, because Vukub's two sons, Zipacna and Cabrakan, still remained to be dealt with. Zipacna was daily employed in heaping up mountains, while Cabrakan, his brother, shook them in earthquake. The vengeance of Hun-Apu and Xbalanque was first directed against Zipacna, and they conspired with a band of young men to bring about his death. The young men, four hundred in number, pretended to be engaged in building a house. They cut down a large tree, which they made believe was to be the rooftree of their dwelling, and waited in a part of the forest through which they knew Zipacna must pass. After a while they could hear the giant crashing through the trees. He came into sight, and when he saw them standing round the giant tree-trunk, which they could not lift, he seemed very much amused. "What have you there, O little ones?" he said laughing. "Only a tree, your Highness, which we have felled for the roof-tree of a new house we are building." "Cannot you carry it?" asked the giant disdainfully. "No, your Highness," they made answer; "it is much too heavy to be lifted even by our united efforts." With a good-natured laugh the Titan stooped and lifted the great trunk upon his shoulder. Then, bidding them lead the way, he trudged through the forest, evidently not disconcerted in the least by his great burden. Now the young men, incited by Hun-Apu and Xbalanque, had dug a great ditch, which they pretended was to serve for the foundation of their new house. Into this they requested Zipacna to descend, and, scenting no mischief, the giant readily complied. On his reaching the bottom his treacherous acquaintances cast huge trunks of trees upon him, but on hearing them coming down he quickly took refuge in a small side tunnel which the youths had constructed to serve as a cellar beneath their house. Imagining the giant to be killed, they began at once to express their delight by singing and dancing, and to lend colour to his stratagem Zipacna despatched several friendly ants to the surface with strands of hair, which the young men concluded had been taken from his dead body. Assured by the seeming proof of his death, the youths proceeded to build their house upon the trec-trunks which they imagined covered Zipacna's body, and, producing a quantity of pulque, they began to make merry over the end of their enemy. For some hours their new dwelling rang with revelry. All this time Zipacna, quietly hidden below, was listening to the hubbub and waiting his chance to revenge himself upon those who had entrapped him. Suddenly arising in his giant might, he cast the house and all its inmates high in the air. The dwelling was utterly demolished, and the band of youths were hurled with such force into the sky that they remained there, and in the stars we call the Pleiades we can still discern them wearily waiting an opportunity to return to earth.
