It is important to note that the "Mocedades" is the last surviving example of Spanish chanson de gesta. From its breakdown were born, according to all indications, the romances. This text is close to those works in its novelistic and imaginative nature and in the majority amount of octosyllabic hemistiches of which the poem is formed. With merely placing the verses in two lines, one per hemistich, and taking into account the fragmentation and holes that the "Mocedades" contains, the nature of the Spanish romance is well explained, with assonance rhyming in the pairs of octosyllables, the beginning "in medias res" and ending interruptions, in addition to an elevated component of novelistic fiction in the recreation of historic events.
