The "Songbook" follows the models of Castilian poems compilations performed earlier, as the "Songbook of Baena" 1445 and the "General Songbook" of Hernando del Castillo, published in 1511. [ 2 ] Garcia de Resende (c.1470-1536), who was a poet , chronicler and courtier in the court of D. Manuel I , gathered a set of almost a thousand poems of 286 authors, of which about 150 are written in Castilian and the rest in Portuguese. [ 2 ] The production period of poems ranges from the mid-fifteenth century to the early sixteenth century. [ 3 ]Unlike the Castilian songbook of 1511, the poems of the Portuguese work are not arranged by themes. [ 4 ]
