The word mural is a derivative of â€˜murusâ€™ meaning wall in Latin. It is the oldest form
of painting and dates back to the prehistoric times. It is three-dimensional in nature
and encapsulates a moment in time. Throughout the centuries, different artists have
used different techniques like oil paint on canvas, ceramic painting, fresco, tempera,
and encaustic painting. In the 20th century, mural painting saw an evolution that
was abstract and expressionistic.
