Venus is the classical Roman goddess of love, often equated with the Greek goddess Aphrodite. She was considered to have been the mother of Cupid. Sexual desire came under her dominion, and so did matters "of the flesh" generally, so that she was the patroness of hunting. The term "venereal" derives from her name. Her name was once a common euphemism for sexual matters in general (for example "The arts of Venus" meant "sexual skills", as well as abilities at attraction and seduction).
