Determining where each piece
goes Although the Parthenon might appear
to be geometrically straight and built from interchangeable parts, it is not.
The ancient Greeks worked subtle curves into the columns, architraves, floors,
and other architectural elements, possibly to make the building appear more
"alive" or to counteract optical illusions of sagging that parallel
lines (like roof and floor lines) can cause. As a result, each of the
Parthenon's 70,000 pieces is unique and fits in only one place.
