 Böhl de Faber's hispanophilia prompted him to collect many works of Spanish literature and build an important library.While travelling in Germany he obtained many of the Aesthetic works of the brothers August Wilhelm Schlegel and Friedrich Schlegel concerning art, literature, and above all Pedro Calderón de la Barca.In 1814, he published an article entitled "Reflexiones de Schlegel sobre el teatro traducidas del alemán" (Schlegel's Reflections upon Theatre as Translated from German) in the newspaper "El Mercurio Gaditano".
