Saffron played a significant role in the Greco-Roman pre-classical period bracketed by the 8th century BC and the 3rd century AD. The first known image of saffron in pre-Greek culture is much older and stems from the Bronze Age. A saffron harvest is shown in the Knossos palace frescoes of Minoan Crete, which depict the flowers being picked by young girls and monkeys. One of these fresco sites is located in the "Xeste 3" building at Akrotiri, on the Aegean island of Santorini—the ancient Greeks knew it as "Thera". These frescoes likely date from the 16th or 17th century BC but may have been produced anywhere between 3000 and 1100 BC. They portray a Minoan goddess supervising the plucking of flowers and the gleaning of stigmas for use in the manufacture of what is possibly a therapeutic drug. A fresco from the same site also depicts a woman using saffron to treat her bleeding foot. These "Theran" frescoes are the first botanically accurate visual representations of saffron's use as an herbal remedy. This saffron-growing Minoan settlement was ultimately destroyed by a powerful earthquake and subsequent volcanic eruption sometime between 1645 and 1500 BC. The volcanic ash from the destruction entombed and helped preserve these key herbal frescoes.
