These publications sought to fill important and paradoxical gaps in the analysis and documentation of those artists who most directly contributed to the renovation of the artistic fact; a renovation with a long trajectory in Catalonia. Sacrifici (Sacrifice) introduces a series of topics apparently tangential to the artistic discourse; so that the artistic discourse, from its specificity, enters into contact, dialogue, even confrontation with other discourses, which may be not so distant, such as the philosophical, scientific, or anthropological, without any of them pretending to be an explanation, transcription or illustration of the others. The most immediate objective of this project of the Centre de Documentació d'Art Actual was to make possible the appearance of a place where these tangential discourses could meet and intertwine.
