For this new exhibition, the works presented are mainly from the collection of tree art of the Czech-born artist and ethnologist Karel Kupka. These works particularly emphasise the arboreal vision of the watery landscapes in Arnhem Land. Bark paintings, poetic texts and sculptures by Yolngu artists from the island of Milingimbi have been selected by their descendants and underline the importance of water in their land. The aim is to show the ecology of these fragile and diverse systems, where human and natural activities have coexisted for thousands of years. For the Yolngu, it is also an opportunity to reveal their sacred cartography which associates their ancestors and myths with the places represented. The voices of the Yolngu accompany the exhibition through original audiovisual documents, as well as an experimental film made by the team of the Milingimbi Art Centre in Australia.
