Born in Marseille around 1700, Charles-François Grenier de Lacroix, known as Lacroix de Marseille, is one of the most important figures in 18th-century French marine painting. Trained in the tradition of Claude-Joseph Vernet, with whom he spent time in Italy, he developed a pictorial style characterised by imaginary harbour scenes in which light, atmosphere and compositional balance play a key role. His work, highly sought after during his lifetime by French, Italian and German art lovers, demonstrates a perfect synthesis between the observation of nature and the classical ideal inherited from the Italian landscape.

This composition belongs to the group of works from his mature period, produced during the 1760s. It guides the eye from the foreground to the horizon through a succession of perfectly articulated planes. On the left, an imposing tree with branches swept by the wind frames a rocky shore dominated by a fortified tower. Several figures — fishermen, travellers and sailors — bring the coastline to life before the composition opens out onto a vast harbour where large sailing ships are moving about, whilst in the background a citadel, a lighthouse and the silhouettes of a harbour town bathed in light come into view.

As in his finest works, Lacroix does not seek to depict a recognisable location but instead composes a fanciful harbour scene, freely combining elements inspired by the Italian and Provençal coasts to create an idealised vision of the Mediterranean. The architecture, the contours of the landscape and the movements of the figures all form part of a carefully crafted composition in which every element contributes to the harmony of the whole.

Light is the true subject of the painting. The delicately rendered clouds allow a silvery glow to filter through, which spreads across the calm waters of the harbour and envelops the buildings in an atmosphere of great gentleness. This mastery of atmospheric effects, combined with a subtle palette of greys, blues and golden ochres, reveals the artist’s full talent for interpreting variations in light – a direct legacy of the classical Italian landscape tradition.

The quality of the drawing, the delicacy of the figures, the rendering of the foliage and the particularly meticulous execution of the ships bear witness to a work created at a time when Lacroix had fully mastered his art. The signature ‘De Lacroix / 1768’, affixed in the lower left-hand corner, confirms that it was executed during this particularly prolific phase of his career.

In spirit, this composition bears a close resemblance to major works held in public collections, notably *Marine de nuit* and *Soleil couchant sur un port* at the Musée des Beaux-Arts in Dijon, *Scène portuaire au coucher du soleil* at the Dallas Museum of Art, and *The Villa of Maecenas at Tivoli* at the Bode-Museum in Berlin. These works exemplify the same quest for a balance between architecture, landscape and light, as well as that serene atmosphere which is one of the hallmarks of Lacroix de Marseille.
