伯唐父鼎是昭王时器,铭文记载了乙卯日王行裸祭和祓祭礼的过程与仪节。周王先射牛牲,次射虎、貉、鹿、狼等野牲,即为祓祭中的射牲礼。射牲的地点在辟池,当为祓祭辟池的水神而射。其行射方法,应是把用作祭祀牺牲的动物放生到辟雍大池中心的丘地上,举行射牲礼时,王乘船在大池中绕丘地寻找目标行射,这样行射也确能起到节观者的效果。也可能是把这些动物驱赶到岸边坡地上,行射时,王乘船在大池中向岸上的动物行射,但这样行射没有前者更能起到节观者的效果。伯唐父鼎随葬于他人墓葬,可能是墓主人盂员生前在征战中得到的。
Botangfu Tripod is the device of Zhao King Period. The inscriptions on it record the process and etiquette of Guan sacrifice and Fu sacrifice by King on the day of Yimao. Zhou King first shoot cattle animal sacrifice, and then shoot wild animal sacrifice such as tiger, racoon dog, deer, wolf and so on, which is the ritual of shooting animal sacrifice of Fu sacrifice. Shooting animal sacrifice was held at Biehi ( a big pond of Biyong) , which may shoot for the Water God of Fu sacrifice in Biehi. There are two hypotheses of the shooting methods. One assumption is that : When the ceremony of shooting animal sacrifice are carrying on, the animals for sacri- fice were released to the mound of the centre of Bichi, and the King searched for the targets around the mound to shoot by boat on the Bichi, which can indeed restrict viewers. The other assumption is that : The animals were driven to the sloping field of the bank and the King shot to the animals by boat on Biehi. However, the later one has a less effect on restricting viewers. Botangfu Tripod is the funerary objects of other people, which may get by the tomb owner Yuan Meng in wars when he was alive.
