Oath of the Horatii is a large painting by the French artist Jacques-Louis David painted in 1784. It depicts a scene from a Roman legend about a seventh-century BC dispute between two warring cities, Rome and Alba Longa. Instead of the two cities sending their armies to war, they agree to choose three men from each city; the victor in that fight will be the victorious city. From Rome, three brothers from a Roman family, the Horatii, agree to end the war by fighting three brothers from a family of Alba Longa, the Curiatii. The three brothers, all of whom appear willing to sacrifice their lives for the good of Rome, are shown saluting their father, who holds their swords out for them. The principal sources for the story behind David's Oath are the first book of Livy, as elaborated by Dionysius of Halicarnassus. However, the moment depicted in David's painting is his own invention. The painting led to the popularization of the Roman salute and also increased David's fame, allowing him to take on his own students. It is now in the Louvre in Paris.Painting: Jacques-Louis David
