《北齐书·本纪·卷四》
戊午，于是在南郊登皇帝位，登上高台烧柴祭祀祷告上天说：皇帝臣高洋胆敢使用黑色的公牛，明确告知天帝：运敷的好坏相互承接，国家的衰亡兴旺交互更替，上天的规律是不问亲近。衹帮助顺应运敷的人。
戊午，乃即皇帝位于南郊，升坛柴燎告天曰：皇帝臣洋敢用玄牡昭告于皇皇后帝：否泰相沿，废兴迭用，至道无亲，应运斯辅。
On Wuwu, he ascended the throne at the Southern Suburb; and, proceeding to the raised terrace, he sacrificed and prayed to Heaven, saying: I, Your subject Gaoyang, venture to use a black bull in sacrificing to You, O great Heaven, and to announce to You that the good and evil of destinies are continuous, and the ruin and prosperity of states alternate, and that Heaven's constant way is impartial, helping only him who accords with its decrees.
