Caravaggio
While he was alive he was very famous, and many artists wanted to paint like he did.  But after he died, most people forgot about him, and didn't care about his paintings.  Hundreds of years later, in the 1900s, people looked at his art again, and saw that he had been very important.  They saw that many other famous artists had tried to paint like he did.  Because so many artists had seen his paintings, and liked how he painted, and tried to paint like he did, he made many artists paint in the Baroque style, too. The Baroque style was very famous for hundreds of years.
