Salvador Alibau is considered to be the most important and original creator with paper in our country. By experimenting with cellulose fibre and paper, Alibau developed his own creative technique: he applied layers of cellulose in water in such a way that, despite being a controlled process, the vagaries of the water’s movements influenced the outcome. This exploration of the media and materials did not respond to a particular aesthetic or formal concern but rather to a poetics of the material and its own dynamics. The two themes that interested Alibau were nature and mathematics, to the extent that he ended up creating the concept of mathemartics, which unites science and intuition. His sculptures in public spaces are also noteworthy and he dedicated his final years to that work.
