The following article contains an answer for the question: What were the names of what Etty was hoping to get £400 for? , can you please find it? 

Possibly because of its size, The Sirens and Ulysses failed to sell at the 1837 Summer Exhibition. In October 1837 wealthy Manchester cotton merchant Daniel Grant, an admirer of Etty who had already commissioned Venus and her Doves from him, met Etty at Heaton Park races and offered to buy The Sirens and Ulysses and Etty's smaller Samson Betrayed by Delilah unseen for a total of £200. Etty was hoping for £400 for the two paintings, but on being told by Grant that his firm had lost £100,000 that year offered a price of £300 for the pair. Grant counter-offered £250 (about £22,000 in today's terms), which Etty refused. On leaving at the end of the evening, Grant suddenly said, "Will you take the money?", startling Etty, who in his surprise agreed. Grant died shortly afterwards, leaving the painting to his brother William, who in turn gave it to the Royal Manchester Institution in 1839.Etty considered the painting to be his best work, insisting that it form the centrepiece of his 1849 Royal Society of Arts solo exhibition. The Royal Manchester Institution was concerned that the painting would be damaged if moved, refusing to allow it to be used in the exhibition until Etty, and a number of influential friends, visited Manchester to beg them to release it. Etty died later that year, and his work enjoyed a brief boom in popularity. Interest in him declined over time, and by the end of the 19th century the cost of all his paintings had fallen below their original prices. As it was rarely exhibited, The Sirens and Ulysses had little influence on later artists, although it is credited as an influence on Frederic Leighton's 1858 The Fisherman and the Syren.
Ulysses and the Sirens is one of those great efforts of my Art achieved in the vigour of my life, I can never make again.
