They crashed into Persian army with tremendous force 

Walter Crane’s illustration depicts the ancient clash between Greeks and Persians, emphasizing the heroic clash of armies. The artist illustrates soldiers with spears and shields, symbols of combat, courage, and civilization's defense against the so-called 'barbarian' hordes. The imagery of the spear, a symbol of power and authority, is not new. Think of the Roman hasta, a symbol of military might. Or even earlier, the Bronze Age spear-bearers, represented in Minoan frescoes. These are all visual echoes of man’s primal urge to dominate. Look at how the figures are arranged; the classical contrapposto posture suggests balance and control, contrasting the chaos of battle. The image resonates with our collective memory of conflict. Through generations, the symbols of war persist, adapting yet retaining their core psychological impact. These representations tap into the archetypes of heroism and conflict, continuing to influence our cultural and artistic expressions.
