PEDRO, D. (Conde de Barcelos).- NOBILIARIO | DE D. PEDRO | CONDE DE BARCELOS | HIJO DEL REY D. DIONIS | DE PORTVGAL. | ORDENADO Y ILVSTRADO | COM NOTAS Y INDICES | POR IVAN BAVTISTA LAVAÑA | CORONISTA MAYOR DEL REINO | DE PORTVGAL.- En Roma: Por Estevan Paolinio, 1640.- [14], 402, [36] p.: 1 gravura; 40 cm.- E. D. Pedro, Count of Barcelos (1287-1354), the natural son of King D. Dinis I, a prominent figure in the peninsular medieval culture. We owe him the compilation of songs by Galician-Portuguese troubadours, the «Crónica Geral de Espanha», from 1344 and the «Livro de linhagens», whose Livro Quatro or Nobiliário can be found here in its rare original edition (the second one was published in Madrid in 1646). The four parts of the «Livro de linhagens» (only fragments of the second and third books have survived) were only published in the 19th century, by Alexandre Herculano, in the collection «Portugaliae Monumenta Historica, série Scriptores». The structure of the copy is developed as follows: 1 - Half-Title(1 f.); 2 - Copperplate print allegorical title (missing, reproduced in photogravure); 3 - Title page (f. [+1]); 4 - Text «Al lector», signed by the printer Estevan Paolinio (f. +2);5 - Dedication to Manuel de Moura Corte-Real, 2nd marquis of Castel Rodrigo, signed by Juan Baptista Lavanha (f. +3 to +4 [blank verse]); 6 - Prologue by Count D. Pedro (f. +5); 7 - Index of Titles I, II and III (f. +6); 8 - Text, beginning with paragraph 16 of Title III (p. 1 to 402); 9 - Small note on the continuation of the Nobiliary (f. ll4 [blank verse]); 10 - Index of surnames [and titles] of this nobiliary (f. +1 to +4v); 11 - Index of the names of the men of this nobiliary (f. a1 to c1). Therefore, the copy does not include the «Notas del Marqves de Montebelo al Nobiliario del Conde D. Pedro» (p. 1 to 46) or the «Tablas» (4 f.) that are missing in most of the known copies. Slightly trimmed copy, with some wormholes: on the inner margin, next to the backbone, of f. 49/50 to f. 169/170, and of f. 327 /328 to the end, sometimes affecting the printed text. Title page with foreign ecclesiastical heraldic stamp and white Salema Garção seal. Recent binding, full natural sheepskin. Samodaes, 2366. Palau, 133210
