“ On the 29th of September 1645 Tirso de Molina became superior of the monastery at Soria, and died there on the 12th of March 1648. It is only within the last few years that it has become possible to give an outline of his life; it will always be impossible for posterity to do justice to his genius, for but a fraction of his plays have been preserved. ”
