Little is known about Legi’s early life. His original name is not known with certainty. It is believed that his Italian name is derived from the French wordLiège which may refer tothe city Liège or the Prince-Bishopric of Liège, in present-day Belgium, where he may have been born. Antwerp has also been suggested as a possible place of birth. Legi moved to Genoa to work as an apprentice in the large workshop of Jan Roos, a Flemish painter who had made a name for himself in Genoa and had married a local woman. Jan Roos specialized in still lifes and market scenes and may have been Legi's brother-in-law. Genoa was at the time an attractive destination for artists since the competition between artists there was less intense than in the leading cultural centres Rome, Florence and Venice, while Genoa was a thriving port city where a large number of potential customers and collectors lived. There was a large colony of Flemish artists who resided in or passed through the city and relied on the network of established Flemish artists and traders to find patrons and commissions. Struck by an illness he moved for treatment to Milan, where he died some time between 1640 and 1645.
Work
Giacomo Legi was a master of the still life and of genre paintings and worked in a style inspired by his teacher Jan Roos. Roos and Legi played an important role in the development of the still life in Italy towards more complex compositions in line with Baroque taste. Legi made a career out of the depiction of single fruit, vegetable, game or fish salesmen and women. It is difficult to determine the chronology of Legi's oeuvre as none are dated. In his mature period his compositions became more elaborate and were characterized by an abundance of figures and details. Characteristic of his work are the rich brushstrokes, the vivid colors and the use of light, with clear chiaroscuro contrasts. During his stay in Genoa, he collaborated with the local painter Domenico Fiasella. Legi's work was much admired and imitated by local painters in Genoa.
