I want to know the answer to the following question:
What did Synods at Milan, Avignon, Liege, Cologne, and elsewhere do?
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?
