Venus of Willendorf is one of the earliest works of art, depicting the planets Mars and Venus embrace in the heavens at night.

The statement is false because the Venus of Willendorf is not a depiction of the planets Mars and Venus embracing in the heavens at night. The Venus of Willendorf is a small, ancient figurine discovered in Austria, estimated to be around 30,000 years old. It is believed to be a representation of a female form, emphasizing fertility and the female body. It does not have any direct relation to the celestial bodies or celestial events.
