Persian-Sassanid art patterns are designs that were created a long time ago in a place called Persia, which is now known as Iran. These patterns usually have bright colors and intricate shapes that repeat over and over again in a beautiful and symmetrical way. Imagine coloring with different colors on a piece of paper, but instead of drawing a picture, you draw lines and shapes that look cool when repeated over and over again. The people who made these patterns took a lot of time and care to make them look perfect, so they are very special and beautiful to look at.
