ONA, Pedro de (on'-yah), Chilian poet, born in Confines, Araucania, about 1560" died in Lima about 1620. He was the son of an officer that died in the war against Arauco under the leadership of Gareia Hurtado de Mendoza (q. v.), and when young Ona had finished his studies in Lima in the College of San Felipe mid the University of San Mareos, he resolved to celebrate the heroic deeds of the Spanish warriors in Arauco in an epic poem. He specially glorified Garcia Hurtado, whom he considered slighted in Ercilla's poem "Araueana." and although many contemporaneous authors attack Ona's poem as over-partial to Hurtado, others, like Lope de Vega, Francisco Figuero, and Diego Mejia, praise it very highly; and it cannot be denied that the versification is excellent, the language beautiful, and the historical facts concise. The work appeared in nineteen cantos under the title "Aranco Domado" (Lima, 1596), of which edition probably only one copy, used by Henry Ternaux-Compans for his translation, now exists" of a second edition (Madrid, 1605) there is a copy in the National library in Lima, and from this an edition was printed (Valparaiso, 1849), which has made this poem widely known. Ona also wrote a poem," Temblor de Lima en el ano 1609" (Lima, 1612), several sonnet, s, and another, rather tedious but well versified, heroic poem in praise of St. Ignacio de Loyola, " Ignacio de Cantabria" (Seville, 1639).
