„The harmony of form consists of the right balance and contrast of vertical, horizontal, oblique and curved lines“*

* Original Language: „L’Armonia della forma consiste nel giusto equilibrio e nel contrasto delle linee verticali, orizzontali, oblique e curve“ (Boito, 1897)

“The quality of the wood is of high importance for processing it, therefore the very first step is choosing the right tree species with high-quality wood for this timber beam.
Traditionally, the tree is chopped down in winter with a hand saw, an axe or springboards and wedges. [..] The next step is cutting the beam from the tree trunk, using traditional hand tools or a mechanical saw.
Anisotropy is crucial when deciding which part is the best part of the trunk to cut out this timber beam. Further, the beam needs to dry to lower the water proportion in it. Once it is dry, this timber beam can be used in various ways in construction.” (Sabrina)

“Early loggers and settlers cut timber near water later which made the transport easier, later on with wood shortages (or in mountainous regions) wood was also transported by ox or horse and sledge. The water made it easy to move timber to the sawmills or to the “joining place”. The process of riding a loge down the timber is called “timber rafting” or “log driving”.
[…] The rafting also allows water to wash out the acids and therefore enhances the quality of the wood – prolongs its life.” (Marie)

„The image depicts the state of degradation of a wooden trunk attacked by the Teredo navalis, a kind of the so-called shipworms or „termites of the sea“. The Teredo is a mollusk species that lives off and inside the tunnels. It digs into the wood as it finds in this its living environment of salty water. The Teredo species is […] capable of causing great damage in underwater wood constructions […]“. (Ana)
