Art
Although some historians dates the start of the trepang industry to 1720, Regina Ganter of Griffith University suggests that the start of the industry may be around 1640. Artistic evidence, like the Arnhem land rock, also suggests that contact may go as far back as the 1500s.
The land rock depicts the extensive boat voyages that spanned thousands of miles around the Australian cost line. The north-west monsoon, which arrived each December, also dictated the semi-permanent locations where the Makassan people would settle. These images likely contribute to narrative stories, which are associated with the ancestral story telling tradition of the indigenous people of Arnhem Land.
Artist Nandabitta Maminyamandja (1911 - 1981) of the
Anindilyakwa people painted Macassan
prau and trepang curing in 1974.
This work is natural pigments on eucalyptus bark and is now on display in the
National Gallery of Australia.
The subject matter includes the communication that the trepanging industry fostered, most importantly early trade interactions. In 1883, the trepanging trade started to decline with the South Australian governments implementation of the trepanging license.
Trepanging-related art work was consistent with the influx of missionaries into the area, as there was a greater demand for secular stories. The missionaries did not encourage the production of ceremonial stories, and they established clear regulations around the subject matter that was depicted and distributed. Therefore, the narrative elements of the Makassan people harvesting sea cucumbers, engaging in the production process, and starting to trade, was culturally educational and desirable for the art market.
