初，漢熹平五年，黃龍見譙，光祿大夫橋玄問太史令單颺：「此何祥也？」颺曰：「其國後當有王者興，不及五十年，亦當復見。天事恒象，此其應也。」內黃殷登默而記之。至四十五年，登尚在。三月，黃龍見譙，登聞之曰：「單颺之言，其驗茲乎！」〈《魏書》曰：王召見登，謂之曰：「昔成風聞楚丘之繇而敬事季友，鄧晨信少公之言而自納光武。登以篤老，服膺占術，記識天道，豈有是乎！」賜登穀二百斛，遣歸家。〉

Shan Yang was the Grand Astrologer of the Eastern Han; the chapter materials do not record where he appears, and the novel does not mention him.
Deeds
In the fifth year of the Xiping era, a yellow dragon appeared in Qiao. Guanglu Dafu Qiao Xuan asked Shan Yang what omen it signified. Shan Yang predicted that a ruler would later rise in that state, and that the yellow dragon would appear again in less than fifty years. He said this was a fulfillment of celestial signs, as recorded in historical sources.
Forty-five years later, a yellow dragon appeared again in Qiao. Yin Deng of Neihuang believed that the words Shan Yang had spoken years earlier had come true, as recorded in historical sources.
