The Ancient Greeks and Romans mastered the use of fragrance to disguise body odor and to make them more attractive. In Greece, the natural oils from eucalyptus, lavender and musk were applied in scented baths and body scrubs. The Roman patricians used fragrant cloths or leather bags hung around their neck to control the smell of body odor and rotting food from disturbing them in places with high-density populations. In the Coliseum, there were mechanisms to feed floral and citrus scents throughout the stands.
