Shown to great success at the Paris Salon of 1863, The Birth of Venus was immediately purchased by Napoleon III for his own personal collection. That same year Cabanel was made a professor of the Ecole des Beaux-Arts.
Cabanel's erotic imagery, cloaked in historicism, appealed to the propriety of the higher levels of society. Art historian and curator Robert Rosenblum wrote of Cabanel's The Birth of Venus that "This Venus hovers somewhere between an ancient deity and a modern dream"; he described "the ambiguity of her eyes, that seem to be closed but that a close look reveals that she is awake ... A nude who could be asleep or awake is specially formidable for a male viewer".
Cabanel was a determined opponent of the Impressionists, especially Édouard Manet,although the refusal of the academic establishment to realize the importance of new ideas and sources of inspiration would eventually prove to be the undoing of the Academy.
Cabanel depicts personality, but in subtle ways through her relaxed posture and sleepy expression. Jenna-Marie Newberry writes of Venus: “The lightest of color used in The Birth of Venus alludes to the lightness and enlightenment of relaxation, amplifying the reclining nude’s placid demeanor and virginity. The contraposto twist of the figure with the melodramatic swoop of the arm over the face comes directly from his previous paintings … Venus herself takes over the entire front of the picture plane. Her hair has been deepened, adding more to her allure and purity.” It is as if the viewer is catching a glimpse of a goddess simply basking in the nature that enfolds her. She is calm, and asks nothing with her gaze. She is a part of her surroundings and the viewer is privy to behold upon the scene. By adhering to the accepted canon of the day, Cabanel produced a quite seductive painting of a mythological beauty presented in a calculated way that was acceptable for viewers at the time of its creation. Following the Salon it was said: “His dark-eyed heroines, thinly painted, usually in muted colors and immaculately drawn, were popular on both sides of the Atlantic”.Wikipedia
