Near Oraibi, Arizona, there is a petroglyph known as Prophecy Rock which symbolizes many Hopi prophecies. Its interpretation is:
The large human figure on the left is the Great Spirit. The bow in his left hand represents his instructions to the Hopi to lay down their weapons. The vertical line to the right of the Great Spirit is a time scale in thousands of years. The point at which the great Spirit touches the line is the time of his return.
The "life path" established by the Great Spirit divides into the lower, narrow path of continuous Life in harmony with nature and the wide upper road of white man's scientific achievements. The bar between the paths, above the cross, is the coming of white men; the Cross is that of Christianity. The circle below the cross represents the continuous Path of Life.
The four small human figures on the upper road represent, on one level, the past three worlds and the present; on another level, the figures indicate that some of the Hopi will travel the white man's path, having been seduced by its glamour.
The two circles on the lower Path of Life are the "great shaking of the earth" (World Wars One and Two). The swastika in the sun and the Celtic cross represent the two helpers of Pahana, the True White Brother.
The short line that returns to the straight Path of Life is the last chance for people to turn back to nature before the upper road disintegrates and dissipates. The small circle above the Path of Life, after the last chance, is the Great Purification, after which corn will grow in abundance again when the Great Spirit returns. And the Path of Life continues forever...
The Hopi shield in the lower right corner symbolizes the Earth and the Four-Corners area where the Hopi have been reserved. The arms of the cross also represent the four directions in which they migrated according to the instructions of the Great Spirit.
The dots represent the four colors of Hopi corn, and the four racial colors of humanity.
