Aphrodite's friends include Helen of Troy, the Graces, Paris and Melanion. Her enemies are Athena, Hestia, Artemis, Hephaestus, Helios and Hera.
Hera and Hephaestus are perhaps Aphrodite's foremost enemies, since Hera arranged Aphrodite's marriage to Hephaestus, the ugliest of the gods, against her will. The Graces are perhaps her best-known friends, as Aphrodite treasured their beauty. Aphrodite is the goddess of love and beauty, so matters like appearance were extremely important to her, and consequently influenced her interactions with others.
Paris, the Trojan prince, deemed Aphrodite the most beautiful of the Olympian goddesses. When he chose her over Athena, he did no favors for the relationship between Athena and Aphrodite.
