CoroagoRepertoire and archive of librettos of Italian melodrama from 1600 to 1900.
Il Corago o vero some observations for staging the dramatic compositions well is a treatise on the staging of the opera performance, compiled around the 1730s by an unidentified author, perhaps Pierfrancesco Rinuccini, son of Ottavio, or Ferdinando Saracinelli. Paraphrasing the title of the treatise, the Corago project intends to offer scholars an ordered and verified information base on Italian melodrama, from the seventeenth to the early twentieth centuries. The reference point of this initiative is the Radames prototype (Repertory and Archiving of Documents Relating to Melodrama And Entertainment), created in 2003 in collaboration with the Department of Music and Entertainment of the University of Bologna: Corago is a first concrete realization of Radames .
