Story
What changed and why it matters
Time can be marked into rock
At Ngaut Ngaut, public education material describes dots and lines understood by Traditional Owners as showing phases of the Moon. Near Sydney, a sequence of engravings in Ku-ring-gai Chase is described as showing the Moon moving through its cycle.
A lunar calendar is a memory device
The practical idea is powerful: a Moon cycle can be remembered through repeated marks, forms and place. Before modern printed calendars, timing knowledge could live in song, story, message sticks, hands, horizon signs and stone.
