Lorenzo De Ferrari (1680–1744) was an Italian painter of the Baroque period, active mainly in his natal city of Genoa.
Lorenzo was the son of the painter Gregorio De Ferrari and Margherita Piola, the daughter of another famous genoese painter, Domenico Piola.
He was prolific in Genoa. Among many works, he painted the glory of the saint the ceiling of the chapel of Sant Ampeglio in the church of Santo Stefano. He painted Esther and Assuero as well as Judith and Holofernes the main altarpiece of the church of San Leonardo. He painted ceiling frescoes on the virtues of the ancient Romans for the Palazzo Brignole. He painted frescoes of Roman gods in the Durazzo palace.
In 1734 he visited Rome where he is said to have met the major painters, Sebastiano Conca and Marco Benefial. Returning through Florence, he met Ignazio Hugford and Francesco Maria Niccolo Gaburri. The latter, who was Luogotenente of the Accademia di Belle Arti in Florence, helped him get awarded honorary membership on 1 August 1734.
After he returned to Genoa, he painted the Assumption of the Virgin for the ceiling of the church of San Sebastiano. He also painted in the Doria palace in San Matteo, near Carloni, and in the church of Gesù, including in the chapel of Saints Stanislao Kostka and Francesco Borgia.
Never married, Lorenzo sometimes wore clerical garb and was nicknamed l’Abate de’ Ferrari.
