Many of the reviews of Seneca's Medea considered the production to be one of the most important and transcendent of its time, a memorable day in the history of the Spanish stage, a view expressed enthusiastically in La Voz:

Seneca's Medea was the pièce de résistance, even a true coup de théâtre, in Spain's own theatrical renovation at the hands of the Xirgu-Borràs Company, with Rivas Cherif at its helm: ‘The modernization of the theatrical landscape that she [Xirgu] fostered in the 1930s in her association with director Cipriano de Rivas Cherif cultivated a dramatic renaissance in the 1920s and 1930s not seen since the Golden Age of Calderón, Tirso de Molina and Lope de Vega’, María Delgado states. Xirgu and Rivas Cherif indeed spearheaded what has been known as the Silver Age of Spanish Theatre. Between 1930 and 1935, while at the Teatro Español, they became the catalyst for a myriad of theatrical synergies. This was the time of the resurgence of theatrical classics and the consolidation of avant-garde international and national authors. They also initiated a profound reform in stage design, and helped to consolidate the director as the orchestrating figure in a production. Medea's own director, Rivas Cherif, would be called in 1935, nearing the end of this era, ‘the first great national stage director’, and ‘nowadays the most prestigious, the most praiseworthy theatre director in Spain’.
