�lvaro de Campos is one of the most influential heteronyms created by Portugal’s great modernist writer Fernando Pessoa. According to Pessoa, Campos was born in Tavira (Algarve) in 1890 and studied mechanical engineering in Glasgow, although he never managed to complete his degree. In his own day, Campos was celebrated—and slandered—for his vociferous poetry imbued with a Whitman-inspired free verse, his praise of the rise of technology and his polemical views that appeared in manifestos, interviews and essays. Here in Margaret Jull Costa and Patricio Ferrari’s translations are the complete poems of Campos. This edition is based on the Portuguese Tinta-da-china edition and includes an illuminating introduction about Campos by the Portuguese editors Jerónimo Pizarro and Antonio Cardiello, facsimiles of original manuscripts and a generous selection of Campos’s prose texts.
