[1] Admitted at an early age into the guild of master-painters, he left them to take part in establishing the French Royal Academy of Painting and Sculpture in 1648[1] and was elected as one of the original twelve elders in charge of its administration.
[2] Some paintings, illustrative of the Hypnerotomachia Poliphili, which were reproduced in tapestry, brought him notice, and his reputation was further enhanced by a series of decorations (Louvre) in the mansion of Lambert de Thorigny, which he left uncompleted, for their execution was frequently interrupted by other commissions.
These last have more personal character than anything else Le Sueur produced, and much of their original beauty survives in spite of injuries and restorations and removal from the wall to canvas.
[1] According to the Encyclopædia Britannica Eleventh Edition, it was considered that Le Sueur's work lent itself readily to the engraver's art, as he had a delicate perception of varied shades of grave and elevated sentiment, and possessed the power to render them.
His graceful facility in composition was always restrained by a very fine taste, but his works often fail to please completely, because, producing so much, he had too frequent recourse to conventional types, and partly because he rarely saw colour except with the cold and clayey quality proper to the school of Vouet; yet his St Paul at Ephesus and one or two other works show that he was not naturally deficient in this sense, and whenever we get direct reference to nature—as in the monks of the St Bruno series—we recognize his admirable power to read and render physiognomy of varied and serious type.
