Lion, 1750s. Looking upward with eyes gleaming and mouth open, the lion conveys wild elegance. The sketch comprises short brushstrokes, and its most striking detail is the thick and plentiful mane. Undefined planes of black make up the lion's longest tresses, but closer to the face, the mane becomes increasingly light. Although the darkest parts of the mane lack precise definition, the chestnut shades of the mane host shadows and highlights that lend a sense of realism. Additionally, varied shades of brown are contrasted by the lighter, creamier shades of white at the lion's muzzle. The life-like nature of this sketch is further communicated by the bright, wet patches on the lion's nose and mouth. Likewise, a bright glimmer in the lion's right eye illustrates its vitality. At the bottom right of the lion, a small signature attributes the painting to Oudry. Although the remainder of the painting has been left unpolished, it probably serves as a valuable study for the completed version that is one of thirteen in a series of animals by the artist.
