Tommaso Maria Ruffo, OP (6 December 1618 – 30 April 1691) was an Italian Dominican friar and prelate who served as Archbishop of Bari-Canosa (1684–1691).

He professed his vows on 22 July 1635 in the monastery of San Domenico Maggiore in Naples, where he lived for three years and also distinguished himself by providing excellent instruction on logic.

The painting, executed in oil on canvas and measuring 80×100 cm, is currently preserved in the Church of San Giuseppe in Piazza Chiurlia, Bari.

Through meticulous details and a masterful use of light, Esposito emphasizes the spiritual authority and dedication of the prelate, paying tribute to his efforts in renewing ecclesiastical discipline and improving clerical education.

The placement of the artwork in the Church of San Giuseppe honors Monsignor Ruffo's historical and spiritual connection to the city of Bari, where he served faithfully until his death in 1691.
