Question: I know that the answer to the question "Who is the person that tells us what happened in the past?" is in "When the Archbishop of Canterbury, Hubert Walter, died on 13 July 1205, John became involved in a dispute with Pope Innocent III that would lead to the king's excommunication. The Norman and Angevin kings had traditionally exercised a great deal of power over the church within their territories. From the 1040s onwards, however, successive popes had put forward a reforming message that emphasised the importance of the church being "governed more coherently and more hierarchically from the centre" and established "its own sphere of authority and jurisdiction, separate from and independent of that of the lay ruler", in the words of historian Richard Huscroft. After the 1140s, these principles had been largely accepted within the English church, albeit with an element of concern about centralising authority in Rome. These changes brought the customary rights of lay rulers such as John over ecclesiastical appointments into question. Pope Innocent was, according to historian Ralph Turner, an "ambitious and aggressive" religious leader, insistent on his rights and responsibilities within the church.". Can you tell me what it is?

Question: I know that the answer to the question "Why might stained glass be more valuable than paintings?" is in "From the early 12th century, French builders developed the Gothic style, marked by the use of rib vaults, pointed arches, flying buttresses, and large stained glass windows. It was used mainly in churches and cathedrals, and continued in use until the 16th century in much of Europe. Classic examples of Gothic architecture include Chartres Cathedral and Reims Cathedral in France as well as Salisbury Cathedral in England. Stained glass became a crucial element in the design of churches, which continued to use extensive wall-paintings, now almost all lost.". Can you tell me what it is?
Answer:
wall-paintings, now almost all lost
