was a very prolific artist, almost every major church in Malta prides itself on his work. He worked very quickly, and according to one of his grandsons he was called ix-xitan tal-pinzell ("devil of the brush"). His performance was enormous; during his lifetime he made more than six hundred different compositions (according to some sources - about two thousand ) consisting of an impressive variety of paintings, drawings, bozzetti, portraits and decorations of church vaults, as well as a number of sculptures and lithography. Unfortunately, many of them were lost during World War II, such as the crucifixion in the Stella Maris church in Sliema. The influence of Romanticism, which the artist became acquainted with in Naples, is evident in most of his early works, such as the painting of the altar of the parish church in Mosta, Our Lady of the Rosary (1870), his first work for churches after his return from Italy, and the Saint Lawrence (1881) and Saint Jerome (1882) in the Sacro Cuor church in Sliema. The latter is widely recognized as a masterpiece of the genre. This style is also visible in the works from 1885: Saint Joseph with Child for the parish church of St. Cajetan in Ħamrun and the Martyrdom of St. Demetrius for the parish church of Maria Bambina in Senglea. Calì has also done several works in collaboration with artist Carlo Ignazio Cortis, including for the Parish Church of St. Lawrence in Birgu and the Church of the Savior in Lija. At the end of the 19th century, he also worked on some side paintings, such as the one for the Church of the Annunciation in Tarxien, and the painting of Saint Dominic for the Porto Salvo parish church in Valletta, where he was baptized Calì has worked on many private home decoration assignments, including a series of four putti entitled The Four Seasons in the entrance hall of Villa Alhambra in Sliema, property of the architect Emanuele Luigi Galizia; He also had a great influence on Maltese society, he painted about fifty portraits of famous people in Malta. This should include the portraits of Cardinal Lavigerie (1884), Cardinal Logue (1886), as well as Governor Richard More O'Ferrall, Marquis Emanuele Scicluna, Giovanni Battista Schembri, Achille Camilleri, Edward V. Ferro, Sir Victor Houlton, Judge Sir Adrian Dingli, Rector of University Napoleone Tagliaferro, Pope Pius IX , Judge Paolo Debono, Count and Countess
