 The frescoes in the Temple of Isis are thought to have been done in the First and Second Style of Pompeian painting, as was the artistic trend at the time.Wall paintings in this style possessed a lot of color, complex, and were representational and influenced by theater.However, when the temple was restored after the earthquake in 62 C.E., the paintings became done in the Fourth Style, which was illusionistic, eclectic, and was a combination of all Pompeian painting styles.
