The ancient Greeks and Romans prized saffron as a perfume or deodoriser and scattered it about their public spaces: royal halls, courts, and amphitheatres alike. When Nero entered Rome they spread saffron along the streets; wealthy Romans partook of daily saffron baths. They used it as mascara, stirred saffron threads into their wines, cast it aloft in their halls and streets as a potpourri, and offered it to their deities. Roman colonists took saffron with them when they settled in southern Roman Gaul, where it was extensively cultivated until the AD 271 barbarian invasion of Italy. Competing theories state that saffron only returned to France with 8th-century Moors or with the Avignon Papacy in the 14th century.
