What goddess threw an apple in the Paris and queen Helen?

The goddess who threw the Apple was Eris, the goddess of discord. She tossed a golden Apple inscribed with "To the fairest" at the wedding of Peleus and Thetis, which led to a dispute among the goddesses Hera, Athena, and Aphrodite. Paris, a prince of Troy, was chosen to judge their beauty, ultimately leading him to award the Apple to Aphrodite, who promised him the love of Helen of Sparta. This event sparked the chain of events that led to the Trojan War.
