The Art of Construction: Millenary Knowledge and Innovative Machineries
In the medieval times they already knew that walls need to be built as perpendicularly as possible in respect to the ground, and to do this they used
the more or less rudimental means they disposed of: modern machineries allow the same proceedings, but with more easiness. Machineries develop,
but the way things must be done always stays more or less the same: after all, construction follows, other than the State laws, the physics laws, that
do not change with the passing of time. The evolution of the construction techniques can be seen through history, as well as in literature: books like
The pillars of the earth by Ken Follett, for example, give a hint of how the construction art could be in the XII century, weaving together the threads of
the story around the construction of a cathedral.
If you think about it, ancient Egyptians built the pyramids with no craves, and the we can say the same for the constructions of Mayas and Aztecs, the
Coliseum and all the ancient and majestic monuments that nowadays we visit as tourists. The construction of some ancient monuments, in fact, keeps
being a mystery, and there are fantastic and science fiction explanations, with alien civilities, special powers and other hypothesis, between science
fiction and paranormal.
Luckily, nowadays building yards have machineries that do not leave doubts on the way they follow to build their constructions: with the various kinds
of cranes and other machineries, nothing is missing to complete the work following physical laws that need no fantastic interpretations. We are far,
though, from being able to consider easy or not fatiguing the job of the modern builders and workmen: despite of the machineries, fatigue is still a lot,
and skill and experience are always necessary.
And if in the XIX century there were ship craves and the modern hydraulic apparatuses, how would it have been to build the Suez Canal and, some
years later, the Panama Canal as well? It would surely no
