Passage: Writing after the fall of Nojpeten, friar Cano described the ultimate fate of Diaz de Velasco and his companions; he claimed to have received the information from interviews with the soldiers from Yucatan who had stormed the Itza capital and from Ch'ol witnesses, although there were no Ch'ol at Nojpeten. Diaz's party arrived at the lakeshore and were told by local Itza that Franciscan friars were at Nojpeten. They were wary at first and asked for proof, upon which an Itza messenger brought them a rosary as a token. Looking across the lake they saw men dressed as friars calling to them to come across, these were Itza dressed in the habits of the two Franciscans who had recently been killed at the island. Diaz and his companions then boarded the Itza canoes, leaving thirty Maya porters with their mules and supplies.Once on the lake the Itza overturned some of the canoes and killed some of Diaz's men; others were wounded and dragged ashore to be killed. Diaz, the Dominicans and two other men were in a large canoe that was not overturned and were taken to Nojpeten where a fierce struggle ensued as Diaz attempted to defend himself with his sword, killing several Itzas. The two other men were immediately killed while the friars were beaten and tied to X-shaped crosses before having their hearts cut out. Across the lake, the Itza attacked the porters guarding the expedition supplies and killed all of them. The Itza killed a total of 87 expedition members, including 50 soldiers, two Dominicans and about 35 Maya helpers. The remains of the small group that were killed on Nojpeten were later retrieved by the Spanish after the fall of the city and were taken back to Santiago de los Caballeros de Guatemala for burial.
Question: What is the first name of the leader of the party that were wary at first and asked for proof?

Ex Output:
Diaz.

Passage: Biographer Hannah Fink estimated that Oliver produced 290 works over a career of 22 years. Of these, public art works are Oliver's best known sculptures. These include Eyrie, created for Adelaide's Hyatt Hotel in 1993, and Magnolia and Palm, commissioned in 1999 by the Sydney Botanical Gardens, as part of the Sydney Sculpture Walk. That same year, Big Feathers was commissioned for the Queen Street Mall in Brisbane. It comprises two large feather-shaped forms suspended above the pedestrian precinct, representing "Queen Street's history of parades as well as the mall's connection between earth and sky".In 2000, Oliver's piece Entwine was a finalist in the inaugural Helen Lempriere National Sculpture Award, while in the following year, Oliver won the University of New South Wales inaugural sculpture commission competition, with her three-metre-high Globe. Other success followed, when Trace was selected for the National Gallery of Australia's 2002 National Sculpture Prize exhibition.In August 2002 she was one of five artists shortlisted by the Australian Government for a project to produce a public artwork celebrating the centenary of women's suffrage in Australia.By the 2000s most of Oliver's output constituted commissioned pieces, whether public or private. The most substantial of these is Vine, a 16.5 metre high sculpture installed as part of the $400 million refurbishment of the Sydney Hilton. Taking twelve months to create and requiring a budget of up to half million dollars, the work was completed in 2005. The sculpture was fabricated from 380 kilograms of aluminium, and assembled by a team of eight Croatian welders.By 2006, Oliver had held 18 solo exhibitions of her work, half of them at Roslyn Oxley9 Gallery, which represented her throughout her career as a sculptor. Only one of those solo exhibitions was held outside Australia: a 1992 exhibition at Auckland City Gallery. However, Oliver was represented in numerous international group shows, including five during the period 1983 to 1984, around the time she completed her master's degree in London. Four of the group shows at that time were in the United Kingdom; the fifth was at the Museum of Traditional Industries in Kyoto. Subsequent international group shows included 'Five Australian Artists' at Brest's Centre Culturale in 1988, the year she undertook an artist's residency in that city. Later group shows of which Oliver was part included 'Prospect '93' at the Frankfurter Kunstverein, 'Systems End: Contemporary Art in Australia', which exhibited in several east Asian galleries in 1996, and the Beijing International Biennale in 2003.
Question: What is the name of the sculpture that was fabricated from 380 kilograms of aluminium, and assembled by a team of eight Croatian welders?

Ex Output:
Vine.

Passage: In February 1828, shortly before his 41st birthday, Etty soundly defeated John Constable by 18 votes to five to become a full Royal Academician, at the time the highest honour available to an artist. By this time, complaints about his supposed indecency were beginning to resurface. All but one of the 15 paintings Etty exhibited at the Royal Academy in the 1820s had included at least one nude figure, and Etty was acquiring a reputation for using respectable themes as a pretext for nudity.For the 1828 Summer Exhibition Etty exhibited three pictures; The World Before the Flood, Venus, the Evening Star and Guardian Cherubs. (The latter was a portrait of the children of Welbore Ellis Agar, 2nd Earl of Normanton, and was the only non-nude painting exhibited by Etty at the RA in the 1820s.) Although similar to his earlier works, they were technically more accomplished. Both The World Before the Flood and Venus attracted positive reviews in the press and were sold during their exhibition for substantial sums, although the purchase by the Marquess of Stafford of The World Before the Flooda work containing scantily clad figures of both sexesdrew a pointed comment in The Gentleman's Magazine that it "will serve to accompany the private Titians of that nobleman". Despite the increasing number of complaints in the press about his use of nudity, respect for Etty from his fellow artists continued to rise, and in 1828 the British Institution awarded him 100 in recognition of his talent.
As soon as the 1828 Summer Exhibition was over, Etty stopped work on other projects to concentrate on a diploma piece, without which he could not become a Royal Academician. This piece, Sleeping Nymph and Satyrs, was presented to the Academy in October, and in December 1828 Etty became a Royal Academician.
It appears to me then that virtuous happiness being our lawful aim in life, that having Academic Rank and Fame the next thing to be considered (if God approve) is to seek that Decent Competency which shall make my latter days comfortable and happy, which I hope if it please Him, to be able to do by the time I am fiftyby occasionally mixing with my historic pictures a Portrait or two, and to vary and extend my spherea classic Landscape or two so that if I can get about 100 a year I may be enabled to retire to my dear native city and spend my latter days in peace.
Question: What is the exact title of the portrait that was the only non-nude painting exhibited by Etty at the RA in the 1820s?

Ex Output:
Guardian Cherubs.
