Then they had to know         stories could be told without words, using only gestures and expressions. To create lifelike scenes, they had to understand perspective, lighting and anatomy.

Large-scale pictures used to be reserved for grand religious or patriotic subjects, but that changed in the 19th century, as artists began creating history paintings based         contemporary news stories.

It presents a scene         the survivors of the wreck on a raft littered with bodies try to signal to a distant ship. When they        ( rescue ), they told how they had been abandoned by their captain, while he sailed to safety in a lifeboat. Starving, they had to eat each other to survive—though this picture makes        look heroic rather than violent. The picture caused a huge outcry. Some people thought the artist meant to criticize the French king,       had been involved in appointing the ship's captain.
