34.19

昭王甲寅四月八日。江河池井汎溢。宮殿大地震動。五色光氣入貫太微遍於西方。王問大史蘇由曰。若何祥乎。對曰。有大聖人生於西方。一千年外聲教及此。王命鐫石。置之南郊大祠前（周書異記○劉恕外紀。昭王時有五色光貫紫微井水溢）。

On the eighth day of the fourth month of the jiayin year under King Zhao, rivers, streams, pools, and wells overflowed; palaces and the great earth shook; and a five-colored vapor of light penetrated the Taiwei constellation and spread across the west. The King asked the Grand Astrologer Su You, 'What kind of omen is this?' He replied, 'A great sage has been born in the west. After one thousand years, the sound of his teaching will reach here.' The King ordered stone to be engraved and placed before the great altar in the southern suburb (Zhoushu yiji. ○ Liu Shu's Waiji: In King Zhao's time, a five-colored light penetrated Ziwei and well water overflowed).
