Don't have chapter and verse on a source, but I understand some
sources say the reason Roman civil engineering created such
durable structures was because the engineer who designed each
arch was required to stand underneath it while the scaffolding
was removed.  The engineers who didn't over-engineer their arches
didn't design many of them.

The thought of doing long division in Roman numerals fills me
with dread--let along manually doing finite element analysis.
