格古要論
古鏡
古人鑄鏡 必用青銅 制作精緻 惟唐鏡紐最高大 故諺云"唐大鼻"
"真子飛霜" 之名來自傳說中的古神仙玄真子以及唐李沇的
方响歌 的最後兩句
敲金扣石声相凌，遥空冷静天正澄。宝瓶下井辘轳急，小娃弄索伤清冰。
穿丝透管音未歇，回风绕指惊泉咽。季伦怒击珊瑚摧，灵芸整鬓步摇折。
十六叶中侵素光，寒玲震月杂佩珰。云和不觉罢余怨，莲峰一夜啼琴姜。
急节写商商恨促，秦愁越调逡巡足。梦入仙楼戛残曲，飞霜棱棱上秋玉。
用音樂表達了人們對超然塵世的追求

The 4 Chinese characters on the mirror are Zheng Zi Fei Shuang. Zhengzi is a legend daoist master. Fei Shuang "Flying frost" might came from a Tang poem. 李沇的方响歌. Together it might be trying to give the image of that music can bring us to aloof realm.
