Opinion: Parthenon's perfection wasn't about correcting illusions

Oxford University professor Alain Goriely challenged a long-held belief about the Parthenon in Greece, arguing that its famed architectural refinements weren’t intended to correct optical illusions.
For centuries, people thought the temple’s curved base and columns compensated for how the human eye perceives straight lines, preventing it from appearing to sag. Goriely’s research suggests these curves are either too small to have been intentionally designed or lack supporting evidence.
The idea that the Parthenon’s builders deliberately countered optical illusions originated with Vitruvius, a Roman writer from four centuries after the temple’s construction. Renaissance scholars mistakenly accepted Vitruvius’s account as firsthand knowledge. Goriely identifies this error as a “supreme knowledge fallacy,” where people assume advanced civilizations must have possessed modern scientific understanding. Ancient Greeks debated the basic mechanics of vision, unsure whether sight involved rays leaving the eye or entering it.
Goriely’s work encourages people to examine the Parthenon closely and question established narratives, suggesting a willingness to reassess assumptions is a hallmark of a great civilization.
