Around this time José de Bragança wrote an introduction brimming with national pride to the Crónica da Guiné (1937), based on the manuscript of the National Library of Paris, where he argued that Infante D. Henrique [Prince Henry the navigator] was the author of the "creation of a Portuguese kingdom of the Algarve and overseas", geared towards the "discovery of new sea routes, peaceful trade and a civilising influence" (Crónica de Guiné, 1937, p. XLIV). By means of an anachronistic back-projection, he thus justified what was thought to be the right to the colonies with arguments quite similar to those advanced by Gilberto Freyre, as if integrating the publication of this "monument" in the commemorations that culminated in the "exhibition of the Portuguese world" in 1940. Costa Pimpão also published an abridged edition of this text, which he studied continuously, in the Clássicos Portugueses collection of Clássica Editora [publishers] (1942), while Alfredo Pimenta published the Crónica da Tomada de Ceuta in the same collection and in the same year. In turn, Torquato de Sousa Soares, who was very active during that period, published the abridged edition of two chronicles by Fernão Lopes in that collection, namely the Crónica de D. Pedro [Chronicle of D. Pedro] (1943) and the Crónica de D. Fernando [Chronicle of D. Fernando] (1945). Apart from these promotional editions, viewed to some extent as propaganda or instrumentalised as such, only Alois R. Nykl, a Czech Arabist living in the United States of America, published a critical, albeit partial, edition of the Crónica de D. Afonso Henriques [Chronicle of D. Afonso Henriques] authored by Duarte Galvão (1942).
In fact, Filipe Lindley Cintra thanked many of these researchers in the preface to his study of the Crónica Geral de Espanha de 1344 [General Chronicle of Spain of 1344] (1951, pp. XIX-XX). Among them, he highlighted the names of Hernani Cidade, Vitorino Nemésio and Harri Meier as the researchers who had influenced him the most. Other researchers were mentioned in the body of the text, his doctoral thesis, which he began in 1947. It was also in the same year, in the post-war period, that a young Lindley Cintra arrived in Madrid to meet Ramón Menéndez Pidal at his home in Chamartín (on the outskirts of the Spanish capital at the time). Cintra received guidance from the Spanish philologist until the end of 1950, when he returned to Portugal; his affiliation to the Pidal philological school remained constant as he always regarded Pidal as his master. The studies conducted by Cintra in Madrid led to the critical edition of the 1400s recasting of the chronicle, the last volume of which was only published in 1990.
