The mixture of Classical and Araucanian motifs in "La Araucana" often strikes the modern reader as unusual, but Ercilla's turning native peoples into ancient Greeks, Romans, or Carthaginians was a common practice of his time. For Ercilla, the Araucanians were noble and brave—only lacking, as their Classical counterparts did, the Christian faith. Caupolicán, the Indian warrior and chieftain who is the protagonist of Ercilla's poem, has a panoply of Classical heroes behind him. His valour and nobility give "La Araucana" grandeur, as does the poem's exaltation of the vanquished: the defeated Araucanians are the champions in this poem, which was written by one of the victors, a Spaniard. Ercilla's depiction of Caupolicán elevates "La Araucana" above the poem's structural defects and prosaic moments, which occur toward the end when Ercilla follows Tasso too closely and the narrative strays from the author's lived experience. Ercilla, the poet-soldier, eventually emerges as the true hero of his own poem, and he is the figure that gives the poem unity and strength.
