Which of the following is not one of the Greek Fates?

Narcissus is not one of the Greek Fates. The Greek Fates, also known as the Moirai, consist of three goddesses: Clotho, Lachesis, and Atropos. Clotho is responsible for spinning the thread of life, Lachesis measures the length of one's life and determines destiny, and Atropos cuts the thread, thus determining the end of life. Narcissus, on the other hand, is a figure from Greek mythology who was known for his excessive self-love and became the symbol of vanity. He was not associated with the concept of fate or the role of the Fates in Greek mythology.
