In Greek mythology, Lachesis, also known as Lakhesis ("disperser of lots"), was the second of the Moirae Sisters, or Moirae. She was the apportioner, deciding how much time for life was to be allowed for each person or being. She measured the thread of life with her rod. She is also said to choose a person's destiny after a thread was measured.
In mythology, it is said that she appears with her sisters within three days of a baby's birth to decide its fate. Her Roman equivalent was Decima. According to Hesiod's Theogony, she and her sisters (Atropos and Clotho) are the daughters of Nyx and Erebus. In other accounts, they are said to be the daughters of Zeus and Themis as well as several other beings such as Chaos and Ananke.
Lachesis is also mentioned in the tenth book of the Republic of Plato as the daughter of Necessity. She instructs the souls who are about to choose their next life, assigns them lots and presents them all of the kinds, human and animal, from which they may choose their next life.
Lachesis, along with her sisters and Hermes, was given credit for creating the alphabet for their people, forced the goddess Aphrodite into making love with other beings, weakened the monster Typhon with poison fruit, persuaded Zeus to kill Asclepius with lightning, and even aided the gods in their war with the Giants by killing Agrius and Thoas with bronze clubs. Even though Lachesis and her sisters were worshiped as goddesses, their representation of fate is more central to their role in mythology.
Her name Lakhesis, literally means "to obtain by lot, by fate or by the will of the gods".
