Celtic art is like drawing and coloring with special shapes and lines that look really cool. Imagine you have a big square piece of paper and you want to make a pretty picture with only some shapes.
The Celts were a group of people who lived a long time ago in Europe. They loved to make things with these special shapes and lines, like their jewelry, coins, and even their houses! They used shapes like spirals, twists, triangles, and squiggles to create their art.
Sometimes their pictures told a story, like a picture of animals or warriors. They also liked to make patterns that went on forever without stopping.
Celtic art was made with lots of care and patience, and sometimes they even used gold and precious stones to make their art extra special. Today, people still use Celtic art to decorate their houses or to make pretty tattoos on their bodies.
