César Miró was born on 7 June 1907, in the Miraflores District in Lima, Peru. He studied in the San Agustín and La Inmaculada schools. He used to escape from his college classes to go visit the Biblioteca Nacional del Perú (the National Library of Peru) and submerge himself in books. At the age of 15, he published the school newspaper “Lightning” and later published his first poems in the magazine “Amauta”. He was friends with José Carlos Mariátegui, but they only discussed art and literature, since they had disagreeing political views.
