Boscán, that had cultivated previously the courtesan lyric, introduced the Italian eleven-syllabes verse and strophes, as well as the reasons and structures of Petrarca like poetry in the Castilian poetry. The poem Hero and Leandro of Boscán is the first that deals with classic legendary and mythologycal themes. On the other hand, his Epistle to Mendoza introduces the model of the moral epistle in Spain, where he exposes the ideal of the stoic wise person. In addition, Boscán demonstrated his dominion of the Castilian by translating The Courtesan (1528) of the Italian humanist Baldassare Castiglione in a Renaissance model prose. In addition, he prepared the edition of the works of Garcilaso de la Vega, although he died before being able to culminate the project, reason why his widow printed the work in 1543 with the title The works of Boscán with some of Garcilaso of Vega.
