«Caupolicán» belongs to Azul… (1888), the book with which Rubén Darío set modernismo in motion. The sonnet portrays the Mapuche chief who, in the legend Ercilla tells in La Araucana, won command by carrying a huge tree-trunk on his shoulder for a day and a night without rest.
Darío carves him like a statue: the arm of Hercules, of Samson, a «Nimrod» striding through the forest until nature and his own people hail him. It is modernismo turning toward America and toward myth, with its characteristic mix of strength and ornament, of ancient history and new music.
The verse is kept in Spanish. Translating it in passing would replace the work with a paraphrase of it.
