Question: Who is the spouse of the author of Queen of the Elephants?

Knowledge 1: North African elephant
The North African elephant (Loxodonta africana pharaoensis) was a subspecies of the African bush elephant (Loxodonta africana), or possibly a separate elephant species, that existed in North Africa north of the Sahara until becoming extinct in Roman times. These were the famous war elephants used by Carthage in the Punic Wars, their conflict with the Roman Republic. Although the subspecies has been formally described, it has not been widely recognized by taxonomists. Other names for this animal include the North African forest elephant, Carthaginian elephant, and Atlas elephant. Originally, its natural range probably extended across North Africa and down to the present Sudanese and Eritrean coasts. [SEP] Knowledge 2: José and Pilar
José and Pilar () is a Portuguese documentary directed by Miguel Gonçalves Mendes following the last years of the Nobel Prize winner José Saramago, chiefly through his relationship with his resolute wife, Pilar del Río. Highly praised by the critics and the audience, the film seems to have accomplished to show the tenderness, the genuine integrity and the deeply concerned humanity behind such controversial figure and his spouse. It gathers sequences from Madrid to Helsinki to Rio de Janeiro and covers Jose and Pilar's life in Lanzarote, their trips around the world (presenting José's books, signing autographs, making speeches) and their most simple, transient and quotidian moments, as for during the period José writes his "The Elephant's Journey". The film was produced by Miguel Mendes' JumpCut (Portugal), Fernando Meirelles's O2 and Pedro Almodóvar's El Deseo.
