The outstanding point of interest in the myth of Vukub-Cakix and his two sons is its terrestrial significance. That they were of the earth as truly as were the Jotuns of Scandinavian mythology there can be no doubt. Like the Jotuns or the Titans, Vukub-Cakix and his progeny are made from the earth, and the parent giant is a living representation of its surface. Xpiyacoc and Xmucane remove his emerald teeth, and replace them with maize grains--surely a mythical interpretation or allegory of the removal of the green virgin turf of the earth, and its replacement by the maize seed. It is further worthy of notice that the maize is placed in Vukub-Cakix's mouth by divine beings. In the third book of the "Popol Vuh" it is stated that the gods gave maize to man. It was, indeed, brought to earth from heaven by the sacred animals. BOOK II. COMMENTED UPON The Second Book of the "Popol Vuh" is the most interesting of the four from a mythological point of view. That it treats of the dealings of the Kichés with the aboriginal people of the district they afterwards inhabited is not unlikely. Although the opinion of Brasseur that Xibalba was a prehistoric state which had Palenque for its capital is an exaggeration of whatsoever kernel of fact may be contained in the myth, yet it is not unlikely that the Abbé, who so often astonishes without illuminating, has in this instance come near the truth. The cliff-dwellings of Mexico and Colorado have of late years aroused speculation as to the aboriginal or directly prehistoric peoples of these regions. The "Popol Vuh" definitely describes Xibalba as the metropolis of an "Underworld"; and with such examples as that of the Cliff Palace Cañon in Colorado before us, it is difficult to think that allusion is not made to some such semi-underground abode. There the living rock has been excavated to a considerable distance, advantage being taken of a huge natural recess to secure greater depth than could possibly have been attained by human agency, and in this immense alcove the ruins of a veritable city may still be seen, almost as well preserved as in the days of its evacuation, its towers, battlements and houses being as well marked and as plainly discernible as are the ruins of Philæ. It is then not unreasonable to suppose that in a more northerly home the Kichés may have warred with a race which dwelt in some such subterranean locality. A people's idea of an "otherworld" is often coloured by the configuration of their own country.
