The editor wishes to express his thanks to the author, Sr. D. Jacinto Benavente, for kind permission to edit these plays; to his father for careful reading and correction of introduction, notes and vocabulary; to Professor John D. Fitz-Gerald, and Dr. Homero Serís, of the University of Illinois, and to Mr. José G. García, of New York City, founder of the newspaper _Las Novedades_, for valuable suggestions on difficult points. Dean Roscoe Pound, of the Law School of Harvard University, kindly furnished suggestions as to the probable interpretation of Emiliano and Triberiano. INTRODUCTION =Benavente's Life.=--Jacinto Benavente y Martínez or Jacinto Benavente, as he is commonly known, was born in Madrid on August 12th, 1866. He attended school in his native city, studied law at the University there, and finally abandoned his thought of a legal career in order to devote himself to dramatic literature. Much intercourse with varied types of people has supplied him with the knowledge of human nature evident in his dramatic productions. Although he has traveled to a considerable extent, Madrid has been the center of nearly all his literary activity, and it is impossible to identify him with any other place. The principal events of his life have been associated with the theater, and are best reviewed in connection with the study of his dramatic career. Mariano Benavente, the father of the author, was a physician and specialist in children's diseases, who came originally from Murcia. His influence upon his son is perhaps noticeable in the respect shown by the latter for the medical profession and in his fondness for children.[i.1] =Devotion to the Stage.=--In an interview published in the Madrid periodical _La Esfera_ (in 1916) Benavente tells us that his affection for the theater was awakened at a very early age. He says that as a boy he took delight in fashioning little theatrical pieces in which he could act, and that his enthusiasm was aroused by the presentation rather than by the composition of such pieces. Even recently[i.2] he declared that he would rather have been a great actor than a writer of plays. In fact, he has been known to appear on the stage with the actress María Tubau and in some of his own productions, one of which was _Sin querer_.
