Achilles’ shield: from ancient art to modern defense

Greece recently named its new multi-level air defense system “Achilles’ Shield”, echoing the famous shield crafted for the hero in Homer’s Iliad.
The shield from the epic poem is best known for its elaborate artistic design, created by the god Hephaestus, depicting scenes of life, war, and the cosmos in five concentric circles. However, the article explores whether the shield was also effective as a functional weapon.
The story recounts how Achilles lent his armor to Patroclus, with instructions to appear as Achilles and repel the Trojan forces. Patroclus disobeyed, resulting in his death and the capture of the armor by Hector. Homer dedicates twenty-four lines to describing Achilles donning the new armor and wielding his spear. During battles, the shield withstood attacks, proving its protective qualities, a spear pierced the first four layers but stopped at the fifth, made of gold.
Over time, the image of Achilles’ shield became a symbol in art and literature. Virgil’s Aeneid adapted the shield to depict Roman history, while Luís de Camões’ Os Lusíadas used it to represent Portuguese imperial expansion. Later, W.H. Auden’s poem “The Shield of Achilles” offered a stark contrast, portraying a shield reflecting the horrors of modern warfare. Now, Greece invokes the shield’s name for its defense system, linking ancient protection with modern military technology.
