## Parthenon myth debunked
A new study shows the Parthenon's curves were not designed to create optical illusions of straightness.

> The Parthenon has been cast as an ultimate trompe-l-oeil, supposedly designed to exploit visual illusions in its curves and refinements.
## Ancient Greek engineering
Professor Alain Goriely analyzed 12 proposed optical corrections using geometry and vision science.

> Current historical and scientific evidence does not support these claims.
## Stylobates curvature
The base rises 2.3 inches (6cm) in the center, but this is not an optical illusion correction.

> Measurements show the sides of the base are not horizontal but form a gentle arc that rises 2.3 inches in the center.
## Column bulges debunked
Columns bulge only 18mm, too small to create noticeable visual effects.

> The columns only bulge by 18mm, hardly perceptible to a typical viewer.
## Vitruvius myth
The 1st-century Roman engineer Vitruvius claimed the curves corrected visual illusions 400 years after construction.

> Vitruvius wrote about the Parthenon 400 years after its construction.
## No optical illusions
The study found no evidence that the alleged visual illusions actually existed.

> The myth of optical corrections has its origin in the writings of Vitruvius more than 2,000 years ago.
## Water drainage theory
The small curves may help water drain away from columns to prevent puddles.

> One possible reason for the curve is that the small gradients help water to drain away.
## 12 corrections analyzed
The study examined 12 proposed optical corrections but found none were supported by evidence.

> At least 12 different optical corrections have been proposed, all following the same basic principle.
## Parthenon's attic
The temple's attic could have stored 260 tons of silver and gold at its peak.

> At its peak, it could have stored 260 tons of silver and gold.
## Attic dimensions
The attic floor spans 62 feet wide by 164 feet long, larger than a tennis court.

> The floor would have spanned an area more than three times that of a tennis court.
## Ancient coin storage
The attic's size allowed coins to be stored without excessive weight on any single point.

> The coins' weight could be spread over a wide area.
## Study conclusion
The Parthenon's curves were architectural choices, not optical illusions.

> The proposed illusions are either unsupported by evidence or too small to have a perceptible effect.
## Key takeaway

Parthenon's slight curves were architectural choices, not optical illusions
