《明史·志·卷三十七》
有乐有舞，虽然是祭祀典礼的常规，但是周、汉时代的制度既不可考证，宋祭祀先蚕，以主管部门代替，又不可引以为据。
夫有乐有舞，虽祀礼之常，然周、汉制度既不可考，宋祀先蚕，代以有司，又不可据。
Dance and music were common in sacrificial rites, but the systems used by Zhou and Han are impossible to verify, and nor can we take as evidence the Song dynasty ritual of sacrificing to the ancestor silkworm, which was performed by the department in charge.
