O piya

The Piya was a Chinese dictionary compiled by Song Dynasty scholar Lu Dian. He wrote this Erya supplement along with his Erya Xinyi commentary. Although the Piya preface written by his son Lu Zai (陸宰/陆宰) is dated 1125, the dictionary was written earlier; estimates around the Yuanfeng era, and Joseph Needham says around 1096.
