Lachesis, derived from the Ancient Greek word 'Λάχεσις' (Lákhesis), means 'disposer of lots' or 'apportioner'. In Greek mythology, Lachesis was one of the three Fates (Moirai), responsible for measuring the thread of life spun by her sister Clotho, thereby determining the lifespan and destiny of each individual. Her role was crucial in deciding how much time each person or being was allotted to live, symbolizing the inescapable nature of fate.
