Passage: The greater attention paid to Spanish American novelists and their international success in the 1960s, a phenomenon that was called the Boom, affected all writers and readers in that period. What mainly brought writers together and focused the attention of the world on Hispanic America was the triumph of the Cuban Revolution in 1959, which promised a new age. The period of euphoria can be considered closed when in 1971 the Cuban government hardened its party line and the poet Heberto Padilla was forced to reject in a public document his so-called decadent and deviant views. The furor over Padilla's case brought to an end the affinity between Spanish American intellectuals and the Cuban inspirational myth.  The Padilla affair is thought by some to have signalled the beginning of the end of the Boom. However, in a significant sense, the Boom has not ended; the writers associated with the Boom have continued to publish books that have been read by audiences far larger than those enjoyed by Latin American writers prior to the Boom. The books of such writers as Carlos Fuentes and Mario Vargas Llosa are widely distributed and translated into other major European and Asian languages to a much greater extent than those of such significant pre-Boom writers as José María Arguedas, Eduardo Mallea or Manuel Rojas.
