Most of Assereto's works depict religious and history subjects, although he also produced some portraits. Throughout the decade in which he was a student, Assereto produced many works in a Baroque idiom, which were close in style and genre. He incorporated drama and emotion in his paintings with the aid of the
chiaroscuro and
sfumato techniques. He continued to improve his technique and style during his twenties and thirties. During his visit to Rome in 1639, he discovered a flourishing interest in realism and Caravaggism. His interest in realism and encouraged him to continue with his detailed description of heads and hands. It may also have revealed to him the possibilities of compositions that depend on chiaroscuro rather than on colour. In 1640, Assereto painted
The Lamentation, a powerful picture which uses a black background and intense shadows to give dramatic effect to Christ's dead body that almost seems to shimmer in the darkness. A work also showing this Caravaggist influence is the
Death of Cato (Musei di Strada Nuova, Palazzo Bianco, Genoa), in which Assereto moved away from his refined style with vivid colours to a bolder, more powerful style where theatrical effects of flaming torches and candlelight emphasize violent emotions. The work also shows the influence of northern Caravaggesque painters such as
Gerrit van Honthorst and
Matthias Stom. shows in the broad and phlegmatic figure of Christ the influence of the
Ecce Homo painted by
Anthony van Dyck in Genoa circa 1625. His late works often depict figures at three-quarter-length and are characterised by a sober realism, a delicate psychological tension between the figures and the grave beauty of the still lifes. These works have been compared to works by Velázquez and Murillo. An example is
Esau sells his birthright (c. 1645;
Palazzo Bianco, Genoa). Gioacchino Assereto was also active as a fresco painter. In the 1640s, he painted frescoes for the Palazzo Granello and commissioned works for the Sant'Agostino church. Only fragments of these frescoes have been preserved. ==Notes==
