The statue was dubbed the "Kritios Boy", after the name of the sculptor believed to have created it. It depicts a standing naked boy with a solemn expression and hair tightly gathered around a ring. The bodyweight is carried on his left leg, while the right one remains relaxed, in the characteristic posture of the so-called “Severe Style”, a sculptural development that emerged after the Persian Wars of 480 BC.
The aftermath of the devastating, but victorious wars against the Persians brings about changes in the society, thought process, and art of Athens. Sculptors now study human body language and try to show the inner world of man. In place of the rigid torso of Archaic-era statues, they juxtapose a more naturalistic stance, with accurate body rendering and plasticity.
The "Kritios Boy", perhaps the earliest creation in the “Severe Style”, is considered a landmark in the history of sculpture, since it marks the transition from Archaic to Classical art. It most likely represents an athlete, the winner of an event in the Panathenaic Games.
