Task: Question Answering
Input (English): Passage: Etty was fascinated with classical artworks such as those he had seen during his recent travels in Italy, and in particular with the Elgin Marbles, a set of major Ancient Greek sculptures taken to London in controversial circumstances in the early 19th century.The Combat: Woman Pleading for the Vanquished is a large painting, 399 cm (13 ft 1 in) across. It depicts a defeated soldier, kneeling in front of another soldier. The defeated fighter strains to free himself from the grip of the victorious warrior, who stands, raising a sword. A kneeling woman clutches the waist of the victorious soldier, raising her face to him to beg him to spare his defeated foe. The defeated warrior has a stronger body, a face more in keeping with the conventions of attractiveness at the time, and a more sympathetic expression, while the victorious man is darker skinned and has an expression of blank fierceness. The vanquished soldier's sword has broken, and lies beside him on the ground.Etty did not base The Combat on any single incident from history or literature, or on any existing artwork, but on his own imagination; this was a highly unusual step to take regarding history paintings, which generally depicted themes from literature or religion. He had been considering the topic as early as 1821, and his plans took shape following his visit to Italy. During this visit Etty had met Antonio Canova and been very impressed by him; The Combat is clearly influenced by his work. As well as drawing inspiration from classical sculpture, he was also strongly influenced by the composition of Old Master works he had seen while in Italy. As with many of Etty's works, the models posed for him separately in his studio, rather than as a group.Etty, writing in 1849, described the purpose of The Combat as "to paint a great moral on the heart [of] the beauty of mercy." Etty's 1958 biographer Dennis Farr points out similarities in the composition of The Combat and John Flaxman's drawing Heracles Killing a Man to whom a Woman Clings, but while Etty and Flaxman were contemporaries at the Royal Academy, it is not known if Etty was aware of this drawing.
In the initial oil study for the defeated warrior (York Art Gallery), Etty gave the character a more defiant appearance than seen in the finished version. In this preliminary sketch he is not on his knees, but thrusts his leg out to brace himself. He has an expression of defiance and determination, rather than the plea for mercy and posture of total defeat shown in the final work.The completed The Combat: Woman Pleading for the Vanquished was exhibited at the Royal Academy Summer Exhibition in 1825. 
Question: What is the last name of the person Etty had been very impressed by?
Output (English): Canova.
