I want to know the answer to the following question:
Where did synods prohibit all hunting at?
All the background I'm provided with is that "Nevertheless, although a distinction between lawful and unlawful hunting is undoubtedly permissible, it is certain that a bishop can absolutely prohibit all hunting to the clerics of his diocese, as was done by synods at Milan, Avignon, Liège, Cologne, and elsewhere.". Is that enough to answer the question?
