The answer in my opinion is “courages”
The introduction of Bach to music had quite an impact. Before Bach, many were ill - tempered and most became well - tempered after Bach. Harmonically speaking, Back's composition were way ahead of time. He introduced unexpected chord changes. He also initiated the keyboard technique that is still used up to date.
I think they adopted Corinthian order, for this type of orders can be seen on many cathedrals around Europe including those in France, Malta (Valletta), etc.
