《宋史·列传·卷一百四十七》
李焘为左史时，曾乞求恢复举行明堂礼仪，说： 南郊、明堂开始没有什么丰厚的施舍，就像在圆坛祭天地一样，可免除出郊浮费。 到这时李焘又重申一次，皇上诏令集体讨论，被朝廷受宠的小人制止。
焘为左史时，尝乞复行明堂礼，谓 南郊、明堂初无隆杀，合视圜坛，特免出郊浮费。 至是申言之，诏集议，嬖幸沮止。
When Li Tao was the Left Grand Historian, he had petitioned to restore the Ming Tang sacrificial ritual, saying that “there were no lavish gifts at the start of the Southern Suburbs or in the Ming Tang, just like the ceremonies at the circular altar to the Heaven and Earth. That would allow us to avoid the waste of going out into the suburbs.” At this point, Li Tao mentioned this again. The emperor ordered that it be discussed by the whole court, but it was opposed by the fawning villains in the court.
