Share Songline, a term coined and popularised by English writer Bruce Chatwin in 1987, refers to a knowledge system – a way of retaining and transmitting knowledge – that is archived or held in the land. They can be visualised as corridors or pathways of knowledge, like Dreaming tracks. The Songlines or Dreaming tracks are often associated with animals (such as a native cat or dingo), natural elements (such as Water Dreaming) or contemporary events (such as the Darwin cyclone of 1974 – the Dreaming provided an explanation for this phenomenon and ceremonies were created). They are also associated with major ancestral beings, such as those embodied in the Seven Sisters Songlines.
