Mining the wealth of new information about manuscript preparation and circulation in the Manos database (manos.net) and about the authorship of theater texts in the CATCOM (catcom.uv.es) portal, this article proposes a comprehensive assessment of the literary career of Andrés de Claramonte. Data analysis rooted in the Manos and CATCOM sites allows for a thorough reconsideration of the staging and manuscript circulation of Claramonte's plays during the seventeenth century. Three points of inquiry underpin my examination. First, I search for evidence of autograph manuscripts by Claramonte. In turn, I survey the indications of his success writing comedias and autos sacramentales, where the professional relationships he established with several theatrical companies between 16l7 and his death in 1626 are of particular interest. Finally, I consider Claramonte's enduring popular appeal after his death.
