This work is developed in the study field of Philology in a dialogue with other areas of knowledge, with the purpose of studying the dramaturgy of Chico Ribeiro Neto. Taking as sources the material documentary that makes up the Chico Ribeiro Neto Collection (Acervo Chico Ribeiro Neto - ACRN), which is part of the Censored Theatrical Texts Archive (Arquivo Textos Teatrais Censurados - ATTC), we present the textual tradition of the three theater texts that form such collection, Branca de Neve e os sete anões, Prova Final and “Em Tempo” no palco, examining the processes of transmission and circulation of such texts within the scope of censorship. Facsimile editions of the testimonies of the three texts were developed, with an interpretative edition being proposed in digital media only for “Em Tempo” no palco. A critical-philological study of the same text was executed, focusing on the intertextual relations presented in the dramatic text in comparison with articles from the newspaper Em Tempo, which were the basis for its writing, through the synoptic confrontation between the dramatic and journalistic texts. We seek to place, in time and space, the aforementioned press vehicle, considering the contents and nature of the ideology propagated in its pages, to bring the social contexts, cultural history of production, transmission and reception of the text of the theatrical play, highlighting the work of the playwright when selecting excerpts from the editions of the referred periodical to compose his text, reading, in a philological perspective, in the fabric of the textual fabric, the moment lived by the society of that time in the period of the military dictatorship. The censored extracts present in the theatrical text will also be analyzed, based on the justifications of the reviewers and studies on press censorship and censorship of public entertainment. The texts will be taken as testimonies of the historical period in which they were written.
