A mathematician's study concludes that the Parthenon's perceived architectural refinements are not optical illusions.

What it means

A mathematician, Alain Goriely, has published a study arguing that the famous curves and refinements of the Parthenon were not deliberate optical illusions designed to correct how the human eye perceives straight lines, but rather a standard feature of ancient Greek architectural tradition. The long-held belief, traced back to the 1st-century Roman architect Vitruvius, claimed that the temple's columns bulge slightly and the base curves upward to prevent it from looking sagging or distorted. Goriely's analysis suggests this was a later misinterpretation and that the builders were simply following established construction practices.

Accuracy & sourcesGrounded

The claim is based on a study by a mathematician, likely published in a peer-reviewed journal or presented as a formal paper, though the reporting does not name the specific publication. The coverage in The Guardian, New Scientist, and Phys.org all cite the same study and researcher, giving it moderate credibility, but as a secondary report without a primary source link, the solidity is limited to the journalist's interpretation of the study. The provenance tier 'aggregated/secondary with no primary cited' correctly reflects that no original paper or dataset is directly referenced.

How new

This is genuinely new reporting from September 15–16, 2026, based on a study published around that time.
