NEBEA presents the first steps in the bibliography of chess through manuscripts, many of them unknown until today. The innovative study of these texts goes beyond the domain of the game. The book offers a wealth of contributions, beginning with the study of the Libro de los Juegos, Seville 1283, by King Alfonso X the Wise, , a fundamental text for the history of chess; the analysis of the different versions in Catalan and Spanish of the famous Liber by Jacobo de Cessolis; and the confirmation, for the first time, of the dating of the poem Scachs d’amor, written in 1475 in Valencia by three celebrated poets – Fenollar, Vinyoles and Castellví; or the study in depth of the books and manuscripts by Vicent, Lucena, Damiano, Reyna, Ruy López and Alfonso Cerón. Furthermore, the book presents in an atypical way the unknown works of three great figures of the period (end of the 19th century and beginning of the 20th century) that marked the new era of Spanish chess: José Tolosa y Carreras, Esteban Puig y Puig and, above all, José Paluzíe y Lucena, to whom the book is dedicated.
