Price guide to antique Renaissance Revival cameo brooches. There was an enormous revival of interest in Classical and Renaissance art from about 1850. Archaeological discoveries in Greece, Italy and Egypt fuelled the imagination of designers. Renaissance art and architecture of the 15th and 16th centuries, itself inspired by ancient Rome, also had a great influence. Classical and Renaissance pieces were sometimes copied quite closely, but often a variety of forms and motifs were combined or reinterpreted. Reference: Victoria and Albert Museum
