Okay kiddo, let's talk about art during a time called the Protestant Reformation and Counter-Reformation. Long ago, people in Europe followed a religion called Catholicism, which had lots of beautiful churches full of artwork. However, some people didn't agree with everything the Catholic church taught and wanted to start their own religion, called Protestantism.
During this time, artwork in churches started to change. Protestants believed that artwork shouldn't be used to worship God, but instead they should focus on reading the Bible and praying. So, Protestants began to take down the paintings and sculptures that had once decorated their churches.
On the other hand, Catholic leaders wanted to make sure that their church was still beautiful and grand. They hired famous artists to create artwork that would show how great God was and make people want to come to church. They called this the Counter-Reformation.
One artist, named Caravaggio, made very realistic paintings that showed stories from the Bible in a brand-new style that was very popular. Another artist, named Bernini, used marble to make sculptures that looked like they were actually moving!
So, that's how art changed during the Protestant Reformation and Counter-Reformation. Protestants didn't want artwork in church, but Catholics still believed in the power of art to help people understand God.
