More on representation of horses in Western Arnhem Land contact rock art.
The horse in the picture at the top, next to Samuel Namundja, was drawn by someone having difficulty sorting horse and kangaroo anatomy. The horse is very kangaroo-like.
In the painting below the artist has a firm grip on horse anatomy, other than issues of scale for head and body. Pipe-smoking riders sharing one horse is not something you would see every day and the intention seems to be humorous and quirky.
It seems reasonable to conclude the painting at the top was drawn by someone who experienced horses only briefly before putting brush to rock while the artist below had spent more time amongst the white people and their beasts.
Both photographs are by David Hancock and are from the Fragile First Impressions exhibition being shown in-house at the conservators conference of the International Council of Museums currently happening in Melbourne.
