But what do they say? I'm picking up "I saw a kangaroo", and maybe also "I saw a thylacine" - or is it a numbat? - and then something about a spotty ovoid Pac-Man with spindly limbs, that one's a scary story.
It's pico-oral mnemonic's that go hand in hand with stories passed down according to the people that had generational custodianship, these, and numerous other rock art sites throughout the Pilbarra and Kimberley (eg: Bradshaw's et al https://en.wikipedia.org/wiki/Gwion_Gwion_rock_paintings )
"Long ago Kujon a black bird, painted on the rocks. He struck his bill against the stones so that it Bleed, and with the blood he painted. He painted no animals, only human-shaped figures which probably represent spirits."
I like the way that ended. More traditional stories should contain vague words like "probably". It reminds me of the part in the book of Revelation where "there was silence in heaven for about half an hour".
Ngolngol the Cyclone Spirit. The figure has long fanned-out earlobes, rain curtaining from raised arms, ancient. Ancient too is his neighbour, Djua, the Devil-Devil Bird with the big penis. His wife killed a little child and cooked it for him. At night, when the women heard his panting coming towards the camp, they would quickly put their infants to the breast so that Djua could not hear the babies’ crying. Here, he is depicted as a hopping scrotum.
Cool. It can't all be myths, though, I seem to remember one piece of more recent rock art depicts sailing ships.
