Asterio Mañanós studied painting in Madrid under Casto Plasencia and Casado del Alisal, but there is little sign of their influence in his oeuvre. He studied in Rome in 1885 under a grant from the provincial council. He received a special mention at the National Exhibition of 1906 and silver medals at exhibitions in Lugo (1896), Zaragoza (1908) and Santiago de Compostela (1909). He was a member of the National Iconography Board and a curator of the art works at the Senate, where he produced a group portrait of the members in the library as a conversation piece (Mañanós Hall at the Senate Building), which was much more successful than the one of the royal visit to the Banco de España.
