《明史·志·卷三十六》
引，是牵引灵车时使用的绳索；披，是用浅绛色带制成的，拴系在载灵柩的车的四根柱上，在旁边执着，以防备倾侧翻倒；铎用铜制造，用来调节挽歌节拍的铃铎。
引者，引车之绋也；披者，以纁为之，击于輀车四柱，在旁执之，以备倾覆者也；铎者，以铜为之，所以节挽歌者。
Leads are the ropes used to pull the hearse; the spread is made of light crimson ribbons, tied to the four pillars of the hearse carrying the coffin, and held on the side to prevent tilting and overturning; and the bells are made of copper and used to adjust the rhythm of the funeral song.
