Abstract art was created at the cusp of the 20th century. It is an art style that breaks away from drawing art as it is represented in real life. Abstract art is about exploring form and color. One could even venture to say that it is artists drawing how they feel. Abstract art isn't about making perfect copies of real life. Sometimes, it isn't even about giving the impression of real life without all the little details. In fact, depending on the artists, abstract art became about the process itself. Representational would mean that you draw what you see. Abstract art is far from that concept.
There were actually several building techniques that were introduced by the Romans, but perhaps the most important was the bridge building technique that allowed bridges to be built without supports.
