This fresco is in the Roman style circa 45-70 CE, similar to the frescoes that decorated the walls of the wealthy villas of Pompeii and Herculeneum. It has a fern garland around the perimeter, which encircles a bridge and a road. I used plaster of paris, which is made of calcium sulfate and reacts similarly to the slaked lime of the originals. I also used watercolors, which bonded to the plaster because of their water base, as opposed to oils, which would have floated on the surface of the plaster. I did several test frescoes to determine the proper mixtures of plaster and how many coats would provide the optimum painting.
