Augusto Intreccialagli was born in Montecompatri (Italy) on February 18th, 1852.
He entered the novitiate of the Roman Province of the Discalced Carmelites in 1868 and was ordained a priest on May 2nd, 1875. His outstanding human and spiritual qualities were immediately noticed by his superiors who over time entrusted him with delicate tasks within the Order.
He was also Consultor of the Congregation of Bishops and Apostolic Visitator of the Salvatorian Friars and Sisters. In 1907 came the unexpected appointment as Bishop of Caltanissetta, which Intreccialagli accepted only by virtue of obedience to the Pope, Pius X. In his diocese, where he was warmly welcomed by the people, he worked for the completion of the Episcopal Seminary, which was inaugurated in 1912, he dedicated himself to the spiritual direction of many lay people and figures of high spiritual stature such as Antonietta Mazzone and Marianna Amico Roxas.
On March 19, 1919, with great suffering, he had to leave his diocese to transfer to Monreale where for some years he had been carrying out the position of Apostolic Administrator, shuttling between Caltanissetta and Monreale. Here he lived the last years of his life and his tireless episcopal ministry was marked by great physical and spiritual suffering.
He died in Monreale the 19th of September, 1924.
The decree on his heroic virtue was promulgated on 22nd of December, 1991.
