On my return to Columbia University in the fall of 1914 for the purpose of continuing my studies, I consulted Professor H.A. Todd in regard to available subjects for a doctoral dissertation. In the course of our conversation he called my attention to a large volume which had been presented to him by Mr. Archer M. Huntington. It was a facsimile copy of the first edition of the Catalan romance of chivalry, _Tirant lo Blanch_. Realizing that here was an opportunity to become intimately acquainted with a work that was made well known, in name at least, by Cervantes in his celebrated _Don Quijote_, I eagerly accepted the suggestion of Professor Todd to examine the book with a view of ascertaining what possibilities _Tirant lo Blanch_ might offer in the field of literary investigation. I immediately began to consult the local libraries, and discovered that no elaborate and extensive study of this work had been made. After I had read the romance my mind was made up that the subject of my dissertation would be based on this Catalan work. I saw in it an abundance of material which provided excellent opportunities for research work. I experienced no little difficulty in selecting the special problems and investigations which were to claim my close and serious attention. Fortunately I again looked over the cards in the Catalogue of the Library of the Hispanic Society, and to my surprise I found a new card which indicated that a critical study of this Catalan work had been published in 1912, the _Estudio crítico de Tirant lo Blanch_ by Givanel Mas. After a careful study of this comprehensive and scholarly production and all other available sources of information pertaining to this subject, I found myself deeply interested in the question of the authorship of this romance, its principal sources, and its historical setting. During the course of my researches and investigations, I have on numerous occasions been the recipient of favors and acts of kindness which, although not bearing directly on my work, nevertheless facilitated my labors and stimulated my efforts. I therefore take advantage of this opportunity to express my most sincere thanks to the following persons: to Doctor Peter H. Goldsmith, Director of the Inter-American Division of the American Association for International Conciliation, and Editor of the _Inter-America_; to Don F. Javier Salas, Consul General of Spain at New York; to Professor H.C. Heaton of New York University; and to Mr. Louis Imbert of Columbia University. To Professor E.B. Babcock of New York University I am deeply indebted for sympathetic encouragement and valuable suggestions, and for his patient reading of the proof-sheets. I am exceedingly grateful to Professor J.L. Gerig of Columbia University for a critical reading of the MS., for suggesting certain improvements, for his good will and helpful advice, and for his final reading of the proof-sheets.
