Giovanni De Min (Belluno, October 24, 1786- Tarzo, November 23, 1859) was an Italian painter and engraver, active in a Neoclassic style.
His parents were of humble origins; his mother, Lucia Schiochet, was the domestic servant of Francesco Maria Colle, a professor of the Atheneum of Padua. In Padua, Demin first apprenticed with Paolo De Filippi, who noting his skills, and with the patronage of the Falier family of San Vitale, had him enrolled by 1804 at the Academy of Fine Arts of Venice, directed by Lattanzio Querena. There he studied alongside Francesco Hayez, and was a pupil of the painter Teodoro Matteini and Pietro Tantini. In 1808, De Min was awarded a stipend from the Academy to study in Rome. There he fell under the influence of neoclassical artists such as Canova.
Returning to Venice, De Min mainly dedicated himself to fresco or panel decoration of houses and salons. His decorations (1817) of mythologic themes in the Palazzo Cicognara in Venice, using designs by Hayez, are now lost. The next year, in collaboration with Hayez he helped decorate the Palazzo of the Count Giovanni Papadopoli in San Marina with depictions of Leda, Diana and Acteon, Salmace and Hermaphrodite, Callisto, Venus and the Graces. He also painted The Four Elements and The Dream of Love for the casa Comello near San Canciano in Venice. Also in 1818 in collaboration with Hayez, and in a commission arranged by the secretary of the Accademia, Antonio Diedo, he participated in the restoration of the Tintoretto canvases in the Ducal Palace. With the death of Angelo Pizzi by 1819, and with the encouragement of Count Cicognara, De Min had been named to professor of sculpture at the Accademia.
