《宋书·本纪·卷一》
下韶说：古人说首先是天地，其次是君臣，所以天上有曰月星辰，神入互相交替，道理起源于蒙昧时代，而行于万代。
诏曰：古称大者天地，其次君臣，所以列贯三辰，神人代序，谅理本于造昧，而运周于万叶。
The imperial edict said: The ancients said that first there was heaven and earth, then there were the ruler and his subjects. Therefore, there are the sun, moon, and stars in the sky and the gods and spirits alternate, and this principle originated in the times of ignorance and has been implemented throughout the ages.
