Among his works as a Hispanist are, among others, his La letteratura spagnola dal Cid ai Re Cattolici (with Alberto Varvaro [de; es; it], 1972).
He was an Academic of the Lincei since 1987, and in 1984 was awarded the Juan Carlos Prize of the Spanish Academy.
From 1976 he collaborated with the newspaper la Repubblica with articles on modern Spanish and Hispano-American literature.
The novel was subsequently republished by Garzanti, included in the series Gli elefanti, and in 2002 published by Arnoldo Mondadori Editore, in the complete works entitled "Fratelli" e tutta l'opera narrativa edited and with a preface by Francesco Orlando.
In addition to the two novels, Samonà wrote the short story Casa Landau (Garzanti, 1990) and the theatrical text Ultimo seminario.
