Step-by-step explanation:
The question refers to the work of George Stubbs, specifically a painting titled 'A Lion Attacking a Horse' from the year 1770. George Stubbs, an artist who lived from 1724-1806, is known for his paintings depicting horses. His work, including 'A Lion Attacking a Horse', aligns with the Neoclassical movement, which is characterized by a return to classical ideas and often portrays subjects with idealized perfection and static poses, drawing on themes from classical history and mythology. By contrast, artists such as Gericault and Remington depicted intense motion and emotion in their works, focusing on powerful horses and brave soldiers in a more realistic and dynamic manner, diverging from the highly polished style of Neoclassicism.
