A comedian named Max Norman is making art galleries fun for visitors. He dresses up as a character named Coco and leads funny, interactive museum tours in London and other cities.
dresses up as= 〜の衣装を着て変装する・扮する
During a tour at an Edinburgh festival last month, Coco taught people about art history using comedy and games. Visitors curtsied to old paintings of kings and queens to learn about their personal lives. They also lay down on the floor to learn about an 18th-century Scottish battle.
lay down= lie down（横になる）の過去形
Max Norman created the tour because of his childhood experience. His mother was an artist and often took him to art galleries across London, where he often felt bored. Now, he uses humor to help visitors enjoy museum art.
because of= 〜が原因で、〜のために（名詞や名詞句の前に置く表現）
