A work of art that uses a tragic Roman tale to arouse feelings of patriotism, self-sacrifice, and civic virtues in its viewers is The Oath of the Horatii.
This painting was created in the 18th century, and was painted by a famous French painter of the time, Jacques-Louis David. At the moment, it can be found in the Louvre in Paris.
Apart from portraying a tragic Roman tale of three brothers swearing before their father that they would fight to the death in order to spare their fellow citizens, the painting also uses the Neoclassical style which is there to replicate the classical one.
