Sidney Nolan: Search for Paradise, currently on at Heide, begins with a magnificent suite of paintings. Towards the left corner of the long opening wall are Nolan’s Woman and Tree and Garden of Eden, both from 1941. They’re clumsy, heavy-handed, said to be influenced by Nolan seeing the work of Georges Rouault reproduced in Art in Australia earlier that year and look like works the great New Zealand painter Colin McCahon was making around the same time.
