poet and dramatist, considered one of Portugal's leading 20th-century playwrights.

Santareno's university studies at Coimbra were completed in medicine. Subsequently he pursued a dual career in Lisbon as a psychiatrist and writer.

Santareno created a stage world reminiscent of that of the celebrated Spanish writer Federico García Lorca. His plays typically deal with the lives of Portuguese fishermen and offer a fusion of popular themes and superstitions and existential concerns. He seeks to identify the national “soul” or prototype of the Portuguese, and his characters oscillate between the sacred and the profane, the physical and the metaphysical. His dramas exhibit a tragic, morose quality that is frequently combined with the erotic.

Among his more than a dozen well-known plays are O lugre (1959; “The Lugger”), O crime de Aldeia Velha (1959; “The Crime of Old Town”), António Marinheiro (1960), O pecado de João Agonia (1961; “The Sin of John Agony”), Irmã Natividade (1961; “Sister Nativity”), and O inferno (1967; “Hell”).
