We are all familiar to mosaics, because mosaic design reflects nature and how we see it. Newspaper and magazine photos are composed of lots of little colored dots, and digital photography is an arrangement of pixels or more colored “tiles”. Early people used mosaics for decoration, especially for homes, gardens, roads and walkways. The making of a mosaic, taking small pieces of permanent materials and forming them in abstract or representational designs is one of the earliest and most permanent art forms.
If we talk about the first mosaics, they were probably pebble walkways. It kept down the dust and mud, made the surface more permanent, and was more comfortable to feet.One can still enjoy ancient pebble walkways in China and Europe, created with different colored and shaped stones arranged in intricate patterns.
Five thousand years ago in ancient Babylon, or what is today Iraq and Syria, the Sumerians took mosaics off the 
prominent design elements, probably reflecting basketry and weaving patterns.
