The programme was dubbed "Reflections from Contemporary South America".
Gamerro mainly dwelt on his first novel Las Islas (The Islands) which deals with the war fought between Argentina and Britain some time back. He read extracts from this novel, explaining what the war (known as the Falklands War) meant to the Argentinean people.
Las Islas will be published in England in 2012 as The Islands by a publisher called And Other Stories Press.
Noorthoorn, who is preparing for the 11th Biennale de Lyon in France, spoke at length about her works in the previous years around the world. Noorthoorn urged artists not to tackle stereotypical issues but to explore and bring in new ideas to their works.
"It is hard to produce or create from a place outside oneself," she said.
Her concept of originality was supported by local author Blessing Musariri who said that even in writing writers have tended to believe that anything negative sells.
Noorthoorn touched on the problems faced by curators around the world, including censorship.
This event was attended by various visual and literary artists who were interested in how best they can bring new aspects to their kind of art.
Gamerro was born in Buenos Aires in 1962. Apart from his first book, he has published El sueno del senor juez, El secreto y las voces, La aventura de los bustos de Eva and short story collection called El libro de los afectos raros. He has also written criticism and translated into Spanish Graham Greene's A World of One's Own, W.H Auden's The Dyer's Hand, Harold Bloom's Poetry and Repression and many others.
The programme "Reflections from Contemporary South America" was the third edition of the National Art Gallery's Harare Conversations, a platform created for the exchange and discussion on diversity of issues relevant to global contemporaries.
With Harare Conversations, the National Gallery of Zimbabwe aims to "reengage the local and international art community" by providing for local artists to dialogue with international artists.
