The Oath of the Horatii is considered one of the finest examples of Neoclassical painting - a major European art movement of the 18th century.
The painting represents a famous myth surrounding the foundation of Rome, when the city was at war with its neighbour, Alba Longa.
To end the war, each city sent 3 brothers to fight it out - the Horatii from Rome and the Curiatii from Alba Longa.
The painting represents the Horatii brothers swearing to their father that they will defeat the Curiatii - or die trying.
The painting is famous for its composition.
The number 3, a symbol of strength and stability, is everywhere : 3 brothers, 3 sisters, 3 arches, 3 distinct groups, 3 distinct parts of the scene…
Most of the lines in the painting guide our eyes towards the tips of the swords - the symbol of the oath.
The men's strength is represented by bold, straight lines.
The women's despair is illustrated by softer, downward-curving lines.
