高僧傳 7.12

7.12

陳郡謝靈運篤好佛理，殊俗之音多所達解。迺諮叡以經中諸字，并眾音異旨，於是著《十四音訓敘》，條列梵漢，昭然可了，使文字有據焉。叡以宋元嘉中卒，春秋八十有五矣。

Xie Lingyun of Chen commandery was deeply fond of Buddhist principles and had a broad understanding of the sounds of foreign customs. He then consulted Rui regarding various characters in the scriptures, as well as the diverse pronunciations and differing meanings. Thereupon [Rui] composed the Shisi yin xunxu (Preface to the Fourteen Sounds and Glosses), listing Sanskrit and Chinese in parallel so that they were clearly intelligible, providing a basis for the written characters. Rui died during the Yuanjia era of the Song at the age of eighty-five.
