New results with regard to the Flora bust controversy: radiocarbon dating suggests nineteenth century origin

Résumé

Many works of art have been attributed to Leonardo da Vinci (1452–1519), the great artist-scientist-engineer of the Italian Renaissance; however, art historians have struggled to find definitive proof to connect Leonardo to these art pieces. The Flora wax bust in the Bode Museum, Berlin, was attributed to Leonardo because her face resembles several Leonardo portraits, but this attribution has the subject of intense debate since the bust’s acquisition in 1909. Using new chemical analyses and absolute 14 C dating, we are able to resolve the question of authenticity. We show that the Flora wax bust is made primarily of spermaceti which was extracted from sperm whales. Therefore, 14 C dating must consider the Marine Reservoir Effect. We have generated a new calibration method and dated the bust to the 19th c. This proves that the bust was not produced during the Renaissance, and thus cannot be attributed to da Vinci, and illustrates that 14 C dating can be applied to unusual materials.
