Study (Young Male Nude Seated beside the Sea) (French: Jeune Homme nu assis au bord de la mer, figure d'étude) is a painting by Hippolyte Flandrin executed between 1835 and 1836. Flandrin had won France's Prix de Rome in 1832, a bursary which provided the winner with a trip to Rome to concentrate on their vocation. There, Flandrin produced this study, which he sent back to Paris in 1837, in fulfillment of the bursary's requirements for the student to submit works in the tradition of various genres. In 1857, Napoleon III purchased the painting, which is now in the collection of Paris's Louvre.
The painting gained attention among contemporary French art critics, and remains one of Flandrin's best-known works, despite being produced relatively early in his career. The subject is an unidentified youth, an "ephebe", who sits nude on a rock with his arms wrapped around his legs and his head resting on his knees, eyes closed. There is a sea in the background, and no distinguishable landmarks locate the figure. The enigmatic scene provides no explanation for the figure's pose: Théophile Gautier (1811–1872) commented that the young man could be shipwrecked on a deserted island, or be a shepherd who has lost his flock. Ultimately, any explanation for this scene is left to the imagination, leading to comparisons with Surrealist art in the twentieth century.
In examining the influence of German aesthetic theory on French art, critic Elizabeth Prettejohn finds that the roundedness of form and "flawless" modeling of flesh would have met with Johann Joachim Winckelmann's approval as an examplar of the beautiful. Prettejohn compares the figure's almost circular pose and sparse framing with that of Leonardo da Vinci's Vitruvian Man.
