Painted in 1904 along the banks of the Marne at Lagny, this luminous canvas captures two young girls in a moment of quiet repose beside the water, rendered with the warm, sun-drenched palette and feathery brushwork that distinguish Lebasque at his most characteristically lyrical. The composition balances intimacy with openness, the figures gently anchored against a shimmering landscape that dissolves into light and reflection. Lebasque, who trained under Gustave Moreau alongside Matisse and Marquet and exhibited with the Nabis before forging his own sunlit idiom, was by this period developing the joyful, domestic sensibility that would come to define his legacy as a painter of childhood, leisure, and the pleasures of outdoor life. At 45.7 by 55.9 centimetres, the work is modestly scaled yet visually commanding, the canvas offering a concentrated display of Lebasque's ability to convey atmosphere through color temperature and loose, confident handling. The subject of children beside water would recur throughout his career, but this early example from Lagny possesses a freshness and directness that speaks to a painter fully in command of his means. The work is signed by the artist and comes in its original frame, adding to its period integrity and presentation. Scholarly credibility accompanies the painting's aesthetic appeal. The work is catalogued in Denise Bazetoux's authoritative catalogue raisonné of Lebasque's paintings, appearing on page 96 as illustration number 186, confirming its place within the accepted and documented body of the artist's work. For collectors seeking a well-documented, visually joyful example of Post-Impressionist painting from a pivotal moment in early twentieth-century French art, this canvas represents a compelling and considered acquisition.
