ATHENS IN THE FIFTH CENTURY BC  257
Also unusual are the deviations from strict vertical and horizontal lines and proportional 
arrangement, the so-called “refinements.” The stylobate, for example, is not flat, but curves 
slightly from the center down to the four corners, as if four people held a sheet by its corners, 
billowed it up into the air, then pulled it down slowly. The centers of the long sides are some 
10cm higher than the corners. Other “refinements” include the thickening of the corner column 
one-fortieth more than the normal column diameter; corner contraction, that is, the setting in 
from the corner, in this case a distance of ca. 0.60m, of the corner columns on the short sides; 
the slight tilt inward of the columns; the upward tapering of the columns; the leaning inward of 
the long walls of the cella; and the slight outward tilt of the entablature and pediments. All of 
these variants are measurable and sometimes can be verified with the naked eye. Many have been 
observed on earlier and later temples, in particular Doric rather than Ionic, but nowhere else 
have they all been combined as here. The precise carving of the appropriate blocks must have 
required much additional time. Why the bother? 
The purpose of these deviations has been much debated. Vitruvius, the Roman architect, who 
had consulted a book about the Parthenon by Iktinos and Karpion, proposed that the architects 
compensated for anticipated optical illusions. Since a long horizontal line seems to sag, it should 
look perfectly horizontal if its middle is raised. Modern commentators have made other sugges-
tions. Perhaps the curve of the stylobate is actually perceived as more pronounced, a deliberate 
exaggeration that makes the stylobate appear larger than it really is. A third interpretation, which 
correlates well with intellectual trends in Classical Athens, favors the tension created between 
expectations and appearances: one expects straight lines, but sees (or senses) curves and tilts. 
The lines of the building thus never quite explain themselves. The building remains a mystery 
that the viewer cannot stop contemplating. The correct answer or answers may be impossible 
to find, but in any case, the abundant use of refinements is a mark of the sophistication of the 
design of this great temple.
The Parthenon: sculptural decoration and the cult statue
The sculptural decoration of the Parthenon was not simply famously beautiful; it had important 
messages to impart. As typical for ancient Greek temples, the exterior carried the figural deco-
ration. The interior was reserved for the cult statue, without additional imagery. The sculpture 
illustrated themes that concerned both the city, its patron goddess, Athena, and its religious prac-
tices, and the continuing need for the forces of order and civilization to fight for victory. Absent 
are any pictures of the rulers or prominent citizens of Athens. This last feature, a characteristic 
of Classical Greek art, contrasts strongly with, for example, the art of the Ancient Near East and 
Egypt, in which the divinity and the monarch are habitually shown in beneficial partnership. 
This lavish and complex program of sculpture took some time to complete. The metopes were 
the first component of the sculptural decoration to be carved, from ca. 447 to 442 BC, followed 
by the frieze and the cult statue (both finished by 438 BC, along with the building itself), and finally, 
the pedimental sculptures (by 432 BC). This, and other details of the construction of the Parthenon, 
we know from building accounts, inscriptions carved on stone which recorded for public appre-
ciation sources of money and exactly for what it was spent. 
The metopes
All ninety-two metopes contained sculpture. Many were destroyed or damaged in the 
explosion of 1687, but enough have survived to give a good idea of subject matter and
