Final answer:
In Euripides' 'Hippolytus', Aphrodite is the deity seen as a foil to Artemis, representing divergent values of love and chastity.
Step-by-step explanation:
The deity seen as a foil to Artemis in Euripides' 'Hippolytus' is Aphrodite. Aphrodite, goddess of beauty and love, plays a central role in the play's narrative. She is portrayed as vengeful and scheming, as her wounded pride leads her to cause the downfall of Hippolytus, who has sworn chastity and worships Artemis, goddess of the hunt and of wild animals. Artemis and Aphrodite have different domains and personalities, which sets up the conflict in the play. While Artemis represents chastity and the wilderness, Aphrodite embodies love, sexuality, and the power of attraction, making them opposites in the context of the play's themes.
