Lope de Vega, the most prolific and, with Calderon, the greatest, of Spanish dramatists, was still alive; and by his applause gave encouragement to the beginner whose fame was to rival his own. The national type of drama which Lope had established was maintained in its essential characteristics by Calderon, and he produced abundant specimens of all its varieties. Of regular plays he has left a hundred and twenty; of "Autos Sacramentales," the peculiar Spanish allegorical development of the medieval mystery, we have seventy-three; besides a considerable number of farces.
