The Moirai, A Compendium of the Ancient Gods

The Moirai — translated as the Fates — were three sister-goddesses who governed the destiny of every mortal from birth to death. Their names and offices were Clotho ("the spinner," who spun the thread of life on her distaff), Lachesis ("the apportioner," who measured out its length), and Atropos ("the unturnable," who cut it with her shears, ending the life). They were daughters of Zeus and Themis, in Hesiod's principal account; in others, daughters of Nyx alone, born without father, signifying their priority over even the rule of Zeus. Plato's myth of Er (in the Republic) gave them their most elaborate philosophical treatment: in his vision they sat upon thrones around the spindle of cosmic Necessity, with Lachesis singing the past, Clotho the present, Atropos the future, and the three weaving the destinies of human lives between them.

The Moirai were inevitable; even the gods could not always alter what they had decreed, though they could occasionally negotiate (Apollo, in Aeschylus's Eumenides, claims to have made the Moirai drunk to extend Admetus's life by allowing his wife Alcestis to die in his stead). Their cult was modest — they were honored at Olympia, at Corinth, and at Sicyon — but their conceptual force in Greek thought was enormous, embodying the Greek conviction that human existence was inscribed in a fabric being woven from beyond the human realm. The English word "fate" descends from Latin fata ("the things spoken"), the Roman counterpart of the Moirai being the Parcae.

Curator’s note

What the sources say, and what later tradition added. The sources for this bay

Hesiod, Theogony 217–222 (daughters of Nyx) and 904–906 (daughters of Zeus and Themis — the contradiction is one of several within the Theogony itself); Plato, Republic 10.617c (the myth of Er); Aeschylus, Eumenides 723–728 (Apollo's claim about the Moirai). The spinning iconography is classical and was much elaborated in Renaissance art. The Roman Parcae (Nona, Decima, Morta) are technically distinct but functionally identical.

When the sources speak

Dated witnesses for The Margins and the Monsters. A date marks when the evidence was written down, not when the belief began. The whole timeline

c. 1600–1100 BCE: Mycenaean palace tablets in Linear B record offerings and divine names, but little continuous myth.
c. 1100–800 BCE: Post-palatial oral traditions and changing cult landscapes precede the surviving alphabetic epics.
late 8th–7th centuries BCE: The Iliad, Odyssey, Hesiodic Theogony and Works and Days give influential but non-exclusive divine orders.
7th–6th centuries BCE: Homeric Hymns, lyric poetry, colonization, and local sanctuary traditions multiply regional narratives.
6th–5th centuries BCE: Orphic, Pythagorean, and mystery materials develop alternative cosmogonies and afterlife doctrines.
5th century BCE: Athenian tragedy and comedy recast heroic houses and divine justice for civic audiences.
4th century BCE: Philosophers, antiquarians, and local historians interpret or criticize inherited myth.
323–31 BCE: Hellenistic poets and scholars systematize variants across an enlarged Greek world.
