Abstract (in English)

From this scientific examination for the preservation of this master-piece of our artistic heritage, based on the bringing-together and confrontation of historic, scientific, and aesthetic elements, the following can be deduced. The agent primarily responsable for deterioration is the salty water (from the canal) which the stone tends to absorb because of its porousness and cracked form, and which in moving toward evaporation surfaces, carries along movable elements and deposits them on the sculpted surface; in the second place and mainly by the accelerated action of this saline migration, we should consider temperature variations produced on the Portal by the direct action of the sun. The porous layer of salt, along with the large quantity of salt deposited, constitutes another serious danger. At the present, the most important factor in deterioration is "man" who by continually touching the stone with his hand, decomposes it and causes it irreparable damage. As treatment, we have set up a plan that includes a programme of attention and periodic care, implying attentive vigilance: 1) Strengthening the stone in order to carry out other work without the Portal suffering further damage as well to avoid the continual deterioration caused by visitors touching it with the hand. Strengthening treatment of the stone implies a previous cleaning that frees it from foreign matter, which necessitates the fixing of the powdery surface in order to control the processes as precisely as possible. 2) Isolating the Portal from all elements capable of communicating the soil's humidity and the salts already contained therein, namely, from the soil and the temple wall on which the Portal rests. 3) Minimising the direct action of the sun on the Portal, while trying not to affect the aesthetic equilibrium of the monument. Let the tact not be lost sight of that in order to save stone that is part of the architectural heritage and hat is exposed to intemperate weather, there is no other formula for the moment than removing it from its original site and transporting it to surroundings with conditions more favourable to its preservation.
