What is the allusion of aphrodite in antigone?

Allusion is a reference to something historical, cultural, or literary significance.

Antigone: Greek mythology, daughter of Oedipus and Jocasta. In Sophocles' Oedipus at Colonus, she and her sister Ismene follow their father into exile at Colonus. When her brothers Eteocles and Polynices killed each other in the war of the Seven against Thebes, Creon, King of Thebes, forbade the burial of the rebel Polynices. Antigone defied him and performed the funeral service. She hanged herself in the cave where Creon ordered her buried alive.

Aphrodite: In Greek religion and mythology, goddess of fertility, love, and beauty. Homer designated her the child of Zeus and Dione. Hesiod's account of her birth is more popular: she supposedly rose from the foam of the sea where Uranus' genitals had fallen after he had been mutilated by Kronos. Aphrodite was married to Hephaestus. She loved Ares, by whom she bore Harmonia and, in some myths, Eros and Anteros. She was the mother of Hermaphroditus by Hermes and of Priapus by Dionysus. Zeus caused her to love the shepherd Anchises, by whom she bore Aeneas. Adonis, in whose legend Aphrodite appears as a goddess of fertility, also won her favors. It was to Aphrodite that Paris awarded the apple of discord, which caused the dispute leading ultimately to the Trojan War. Worshiped throughout Greece, she was the goddess of love, marriage, and family life; she was also worshiped as a war goddess, as at Sparta, and as a sea goddess and patroness of sailors.
