      祖莹，字元珍，范阳遒人也。父季真，位中书侍郎、钜鹿太守。
      莹年八岁能诵《诗》《书》；十二为中书学生。耽书，父母恐其成疾，禁之不能止。
      常密于灰中藏火，驱逐僮仆，父母寝睡之后，燃火读书，以衣被蔽塞窗户，恐漏光明，为家人所觉。由是声誉甚盛，内外亲属呼为“圣小儿”。尤好属文，中书监高允每叹曰“此子才器，非诸生所及，终当远至。”
      时中书博士张天龙讲《尚书》，选为都讲。生徒悉集，莹夜读书劳倦，不觉天晓，催讲既切，遂误持同房生赵郡李孝怡《曲礼》卷上座。博士严毅，不敢还取，乃置《礼》于前，诵《尚书》三篇，不遗一字。 讲罢，孝怡异之，向博士说，举学尽惊。后高祖闻之，召入令诵五经章句，并陈大义，帝嗟赏之。以才名拜太学学士。
