《宋书·志·卷十六》
古代夏、殷两朝以尊崇天神为吉祥，周武王时以鱼跃入舟、火化为乌为美事，都称为善美；然而符瑞的显现，实物的盛多，没有像今天这样丰富的。
昔夏、殷以丕崇为祥，周武以乌鱼为美，咸曰休哉；然符瑞之应，备物之盛，未有若今之富者也。
Ancient Xia and Yin dynasty favored gods as auspicious, when the king of Zhou subdued bandits, fish leapt into a boat, the fire turned into a crow, all considered to be good omens; however, the appearance of auspicious signs and the prosperity, have never been as rich as this.
