For this double purpose, to witness the archbishop's declaration and to make the recognition, a great council met at Clarendon, near Salisbury, towards the end of January, 1164. Some questions both of what happened at this council and of the order of events are still unsettled, but the essential points seem clear. Becket gave the required promise with no qualifying phrase, and was followed by each of the bishops in the same form. Then came the recognition, whether provided for beforehand or not, by members of the council who were supposed to know the ancient practice, for the purpose of putting into definite form the customs to which the Church had agreed. The document thus drawn up, which has come down to us known as the Constitutions of Clarendon, records in its opening paragraph the fact and form of this agreement and the names of the consenting bishops. It is probable, however, that this refers to the earlier engagement, and that after the customs were reduced to definite statement, no formal promise was made. The archbishop in the discussion urged his own ignorance of the customs, and it is quite possible that, receiving his training in the time of Stephen and believing implicitly in the extreme claims of the Church, he was really ignorant of what could be proved by a historical study of the ancient practice. The king demanded that the bishops should put their seals to this document, but this they evidently avoided. Becket's secretary says that he temporized and demanded delay. Henry had gained, however, great advantage from the council, both in what he had actually accomplished and in position for the next move.
