What Kelly proposes in her new book The Memory Code is that sites such as Stonehenge and the Nasca lines are actually memory spaces.
The Euahlayi would memorise star maps at night and learn the songs that talk about their relationship to the land. Each star was associated with a landscape feature, such as a waterhole.
Later in the year, they would sing the song as they travelled across country by day. These songline routes became the foundation of some of our highway networks that criss-cross the country.
Rather than navigating by the stars, the stars themselves serve as a memory space.
poetry is the memory code.
