In traditional Balinese society, activities are divided by gender and historically painting and sculpture were male territory. Of course, there have always been women painters but it was difficult for them to be shown and get their deserved recognition. In 1991 British-born Mary Northmore Aziz converted a house into a gallery for female artists. A number of the Balinese artists that she shows have been heavily influenced by one of the recognized "traditional" styles. Ni Made Suciarmi and her niece, Supini, two of Bali's top classical painters, still work on cloth polished with rice flour and grind their own pigments. Ni Wayan Warti works in the tradition of Batuan, creating paintings full of the eerie supernatural quality the Balinese call tenget, while Gusti Agung Galuh's paintings show a strong influence from Walter Spies.
