We learn from the sculptures and mural paintings that adorn the walls of the palaces at Chichen-Itza and Uxmal that king _Can_ (Serpent) the founder, or maybe the restorer, of these ancient cities, had three sons whose names were _Cay_ (Fish), _Aac_ (Turtle), and _Coh_ (Leopard), and two daughters, _Moo_ (Macaw), and _Nicté_ (Flower). It was the law among the Mayas that the youngest of the brothers should marry the eldest of the sisters to insure the legitimate and divine descent of the royal family. This same custom of princes of royal blood marrying their sisters existed among the Egyptians from the earliest days, and it became in after times general; such alliance being considered fortunate. It also prevailed with the Ethiopians, the Greeks, those of Mesopotamia in the time of the patriarchs, the Peruvians, and many other nations. Prince _Coh_ was a brave and successful warrior; at the head of his followers, whom he had often led to victory, he had conquered many nations and greatly added to the glory and extent of the Maya empire. Being the youngest of the brothers, he was the one who had to marry Moo, the eldest of the sisters. She, on her part, loved him dearly and was proud of his exploits. After the death of King Can, their father, the country was parcelled among his children. Moo became the queen of Chichen, and many of the lords swore allegiance to her. After her death she received the honors of apotheosis; became the goddess of fire, and was worshiped in a magnificent temple, built on the summit of a high and very extensive pyramid whose ruins are still to be seen in the city of Izamal. [Illustration] _Aac_, the second son of king Can, was also in love with her. To his lot had fallen the ancient metropolis _Uxmal_, "the three times rebuilt." His headless and legless statue is still to be seen over the main entrance on the façade of the palace known as the "House of the Governor," at that place. The flayed bodies of his two brothers and his eldest sister are at his feet; their heads hang from the belt round his waist: and the ruins of his private residence, ornamented with turtles,—his totem—yet exist at the northwest corner of the second of the three terraces on which the palace is built. The law of the land and her own predilection for Coh were insurmountable barriers that prevented Aac from marrying Moo. He was not a warrior but a courtier. He spent his life in idleness amidst pleasures and frivolities. Still he was envious of the fame won by his younger brother; jealous of him because of the love of the people, and still more of that of his sister and wife. He allowed his evil passions to gain the mastery over his better feelings. He incited a conspiration against the friends of his childhood, with the object of killing his own brother, to obtain forcible possession of the sister he so much coveted, seize the reins of the government, and become the supreme lord of the whole empire.
