Step-by-step explanation:
The most common attribute of Aphrodite in artwork, based on the lecture notes provided, is her depiction in the Venus pudica pose. This pose is characterized by the goddess being shown bare with her hand covering her genitalia, often with a gesture that implies modesty. Aphrodite of Knidos by Praxiteles and the later Venus de Milo by Alexandros of Antioch both embody this portrayal, with the Aphrodite of Knidos standing in the contrapposto stance and having an S-curve figure that became signature elements of Praxiteles' sculptures. Original Greek sculptures, including those of Aphrodite, would have been painted and adorned with metal jewelry, features now lost to time. Aphrodite's sculptures are celebrated for their sensuality and humanity, setting a new precedent for the depiction of female figures in classical art.
