| Summary: | Fans, called tah’i, coming from the Marquesas Islands, are understood to be prestigious objects but they remain mysterious, particularly for the identification of the vegetal fibres from which they were made and the technical know-how of their fabrication, which has now been lost. These difficulties call for new investigative methods. Our study will take a look at a collection of eight fans preserved in the Paris Musée du quai Branly-Jacques Chirac. The fans were studied with an interdisciplinary approach comprising historiography, a technical study of the fabrication processes and comparative anatomy. Biological and cultural information has been acquired in parallel. A 3D digital microscope was clearly the appropriate tool for the identification of the fibres, using direct observation without any destructive extraction of samples. It also became apparent that the microscope’s range of high-quality lenses and its 3D restitution process, associated with X-rays tomography, was also a suitable tool for studying the manufacturing processes of the fans, allowing for better integrated sessions of analysis. A present-day reference collection of possible taxa has been created in order to identify the key diagnostic characteristics (plant specimens from the Muséum national d’Histoire naturelle and taxa collected in situ). Experimental sessions with local basket makers were also used to understand how the different plant fibres were chosen and to record the physical gestures of the craft processes. The pictures and measurements taken during this study can perhaps offer some compensation for the fact that none of these fans survive in the Marquesas Islands themselves. They might also underpin the development of revived fabrication techniques. |
