The greatest and most celebrated of all the Mexican games was that called the Flyers. They first sought out the loftiest tree in the forest, stripped it of its branches and bark, and set it up in some public square. On the top they fixed a sort of movable cap or cylinder, from which hung a square frame, made of four planks. Between the cap and frame they fastened four strong ropes, long enough to reach to the ground, passing through four holes in the planks. These ropes they twisted round the tree, until their ends were nearly up to the frame. Four men, who were called the flyers, disguised like eagles, herons, and other birds, ascended the tree by means of a rope which was laced about it from top to bottom, and took hold of the ends of the rope. The force with which they swung off from the frame caused it to turn round, and as it turned, the ropes which were twisted around the tree began to unroll, and of course became longer at every revolution. All this time the wooden cap continued to turn round, being fastened to the frame; but, nevertheless, a man kept dancing upon it, waving a flag or beating a little drum, as unconcerned, as though a single false step would not dash him to instant destruction. When the ropes were so far untwisted that they almost reached the ground, some other actors, who had mounted on the frame, threw themselves off, and slid down along the ropes to the earth, amid the applause of the spectators. The Mexicans did not paint, like other nations, merely for the purpose of preserving the form of persons or things which must soon pass away, or of affording pleasure by the representation of the beautiful, the grand, or the terrific. Their painting was their writing. By means of this art they represented their history, their religious rites, their laws, and everything which they deemed worthy of being recorded for the instruction of their descendants. This manner of writing was, to be sure, very imperfect, but it answered all the purposes to which it was applied. They wrote on paper which they made of the bark or leaves of certain plants. Had all the paintings of the Mexicans been preserved, we should have had a complete history of the nation, from the earliest period to the arrival of the Spaniards. But the zeal of the Catholic priests was the cause of the destruction of almost all these valuable records. Suspecting that they contained the idolatrous precepts of the Mexican religion, they thought that they could best promote the cause of the true religion by destroying all the writings of the natives. Accordingly, they collected them with the greatest diligence, and burnt them in the public square, to the great grief of the Mexicans.
