She participated in numerous exhibitions during her career while working as an artistic director for the state television company.
[3] She illustrated many books as well, such as Erlom Akhvlediani's children's work The Story of a Little Mouse.
Oniani began publishing her writing in 1968; she dealt with such taboo topics as religion and erotic subjects, and soon caused a sensation with her work.
Nevertheless, although several collections of her work were published, she was publicly noted more for her artistic endeavors than her writing, which circulated mostly privately; it was only after her death that her poetry began to receive wider attention.
Some of her writing has been translated into German and published,[2] and several of her paintings may be found in the collection of the Georgian Museum of Fine Arts.
