In the text various episodes cross, each only weakly related to the others. The latest of the Hispanic epic poems, it appears to have been the last draft composed from diverse material, in as much chronicles as epics from oral tradition, perhaps even a proto-Spanish romance of El Cid. This is confirmed by the around dozen holes existing within the text, some very notable. In particular, a prominent one causes the interruption of the manuscript, which forces the conjecture of the ending based on the chronicles that transmit earlier versions of the poem.
