From proposition to gesture: dialogues about Primeira Pedra by Matheus Rocha Pitta aims, through a deep analysis about Primeira Pedra (2015) by Matheus Rocha Pitta, to articulate the multiple layers of understanding requested by the work, as well as to investigate the dynamics that involve its assembly and exhibition. The current investigation, although non-chronological, takes into consideration the artist s repertoire, which enables a deep analysis on the main object of this study. However, beyond being a study of the artist, this research allows us to outline dialogues on relevant subjects for contemporary artistic production, since not only Primeira Pedra, but also other works by the artist, gather key concepts for the History of Art: we are spontaneously led to a critical reflection on authorship, reproducibility, valuation and participation. This seems to be one of Rocha Pitta s qualities: providing urgent content for nowadays in a subtle manner, stimulating the spectator to elaborate critical interpretations of everyday matters, made available by the artist through a gesture. At this point, it is understood that in addition to an updated notion of the status of the spectator, the proposal for Primeira Pedra - which implies a transaction of a sculpture signed and dated by an ordinary stone - also suspends the traditional idea of sculpture. In light of this, this research points out and elaborates on the categories elucidated by the work in question, considering its reassemblies in institutions of different natures, articulating it not only with Rocha Pitta s productions, but also with other artists works, which somehow intertwined with Matheus Rocha Pitta s trajectory.
