Leonardo Castellani was an Argentine priest, essayist, novelist, poet and theologian. Born in Reconquista, Santa Fe, Castellani was ordained as a Jesuit priest in 1930, he studied Philosophy and Theology in Rome. Back in his country, he worked in the Catholic press and went into politics as a representative of Catholic nationalism. He was among the candidates of the Alianza Nacionalistaparty for a seat in Congress in the 1946 elections. Between 1946 and 1949 he clashed with his own Society of Jesus, who promptly sent him to a two-year confinement in Manresa. After his petition to assist his brother's funeral was refused, Castellani escaped from Manresa returning to Argentina. He was then expelled from the order and suspended from his functions as a priest, which were repristinated in 1966. Castellani has left a considerable bulk of essays, novels, tales and poetry. Among the wide range of subjects he tackled, his religious writings deserve a special place, especially his sermons on the gospels and his exegesis of John's Apocalypse. His prolific intellectual production includes a commented edition of St. Thomas Aquinas’ Summa Theologica. One of his last books is dedicated to Søren Kierkegaard, for whom he nurtured a great admiration. Father Castellani's style is forceful, lively and of an acute intelligence. Considering his right wing sympathies earned him the dislike of the progressive left wingintelligentsia on the one hand while his conflicts with the Jesuit order spawned the mistrust of weighty sectors of the Catholic world, it is no surprise that Castellani's work has never reached the position it deserves among Argentine letters. Apart from a restricted group of fervent admirers such as Argentine writersRafael Squirru and Sebastian Randle and Cardinal Antonio Quarracino who consider him one of the foremost Argentine intellectuals of the Twentieth Century, it would not be exaggerated to say that Castellani's writings are still widely ignored in his own country.
