Memory technologies in worlds without writing

Cultures without writing are referred to as ‘non-literate’, but their identity should not be associated with what they don’t do, but rather with what they do from necessity when there is no writing to record their knowledge. Cultures without writing employ the most intriguing range of memory technologies often linked under the academic term ‘primary orality’, including song, dance, rhyme and rhythm, and story and mythology. Physical memory devices, though, are less often included in this list. The most universal of these is the landscape itself.

Australian Aboriginal memory palaces are spread across the land, structured by sung pathways referred to as songlines. The songlines of the Yanyuwa people from Carpentaria in Australia’s far north have been recorded over 800 kilometres. A songline is a sequence of locations, that might, for example, include the rocks that provide the best materials for tools, to a significant tree or a waterhole. They are far more than a navigation aid. At each location, a song or story, dance or ceremony is performed that will always be associated with that particular location, physically and in memory. A songline, then, provides a table of contents to the entire knowledge system, one that can be traversed in memory as well as physically.

Enmeshed with the vitalised landscape, some indigenous cultures also use the skyscape as a memory device; the stories of the characters associated with the stars, planets and dark spaces recall invaluable practical knowledge such as seasonal variations, navigation, timekeeping and much of the ethical framework for their culture. The stories associated with the location in the sky or across the landscape provide a grounded structure to add ever more complexity with levels of initiation. Typically, only a fully initiated elder would know and understand the entire knowledge system of the community. By keeping critical information sacred and restricted, the so-called ‘Chinese whispers effect’ could be avoided, protecting information from corruption.

Rock art and decorated posts are also familiar aids to indigenous memory, but far less known is the range of portable memory devices. Incised stones and boards, collections of objects in bags, bark paintings, birchbark scrolls, decorations on skins and the knotted cords of the Inca khipu have all been used to aid the recall of memorised information. The food-carrying dish used by Australian Aboriginal cultures, the coolamon, can be incised on the back, providing a sophisticated mnemonic device without adding anything more to the load to be carried when moving around their landscape. Similarly, the tjuringa, a stone or wooden object up to a metre long decorated with abstract motifs, is a highly restricted device for Aboriginal men. As the owner of the coolamon or the elder with his tjuringa touched each marking, he or she would recall the appropriate story or sing the related song.
And so on.
