《宋史·志·卷一》
臣曾经普遍考察了古今仪象的方法，《虞书》上所说的璇玑玉衡，只有郑康成粗略地记下它的方法；到洛下闳制作圆仪，贾逵又加上黄道，它的详细情况都没有保存在书籍中。
臣尝历考古今仪象之法，《虞书》所谓璿玑玉衡，唯郑康成粗记其法，至洛下闳制圆仪，贾逵又加黄道，其详皆不存于书。
Your subject has widely studied the methods of ancient and modern astronomical instruments. The Xuanyi and Wang Heng [instruments] mentioned in the Yushuji are only described briefly in Zheng Kangcheng's notes. When Luoxia Hong made the Yuanyi, Jia Kui added the ecliptic to it, but the details have not been recorded in any text.
