(...) Otávio stopped engraving and started weaving. The papers on display here are like webs: the shapes, lines, colors and textures that we notice on them were not placed on the surface; they are intrinsic to the paper, as if merging with it in order to be born together. Like in a web, what fascinates us the most is discovering the perpetual and apparent entanglement that can be discerned at a glance.
(...) In Roth's paper, the weft is present and palpable. This presence of weaving fascinates us and suggests a certain transparency, blending the boundaries that we try to impose on things. His papers are not just engravings. They remain on the threshold, creating their own space. They are born of pleasure and are not shy of exposing their process; on the contrary, they reveal the presence of the blind intelligence of hands, which imposes itself during the act of doing. And this is where we can more clearly discern Otávio's artistic personality, which has always been characterized by the verb "to do".
