Daughter of highly regarded elder and women's business story keeper Barbara Price Mtjimbana, Jacinta went to primary school at Stirling Station near Tennant Creek. Later Jacinta went to Kormilda College in Darwin for high school as did most of her sisters, The Numina Sisters. Jacinta is one of the elder sisters of these six well known desert artists and also has three brothers. Like her sisters and mother she comes from a long line of desert painters of the contemporary Aboriginal art and dot-dot central desert movement from well renowned painter aunties: Gloria and Kathleen Petyerre, who are well established artists in Alice Springs.
Jacinta lives in Darwin where her works are collected by universities, art dealers and art lovers from around the world. She regularly travels back to home lands to visit family.The Bush Medicine Leaves Dreaming knowledge story is a popular theme of the Numina Sisters. Many women from the Peytre, Mambitji and Numina family name hold custody of the story and knowledge keepers of painting series-themes such as Bush Medicine Leaves, Bush Tucker, Seeded, Soakage, Women's Ceremony etc - in common with other skin groups across the vast arid creek beds and red sand of central Australia.Subjects of importance in the theme-series painted are various bush tucker. Plant foods include wild berries, plums, onion, yam, seeds etc. Many animals can be depicted as food source or as totems such as Thorny Devil Lizard and Dingo Tracks.Women's Ceremony, Awelye Body Art Ceremony are mostly painted by senior ladies but younger women need to know it from a young age. Some themes such as Bush Tucker can be open and universal, but others can be secret and significant cultural ceremonies. Knowing, carrying and reinforcing these stories gives respect for Country and ancestors and shows responsibility and care of holding such stories to keep the stories and traditional practices alive. The knowledge must be retold repeatedly and handed on.
The Numina Sisters have all been taught to paint by their earlier elder painter grandmothers, mother-auntys, and cousin-sisters connected across the Central Desert region. Their mother's and grandmother's Country is in the bush and in remote Stirling Station.
