The classical triad of the Moirai may have contributed to this image; namely of Clotho, the 'Spinner,' who spins the life thread; Lachesis, 'Disposer of Lots,' determining its length; and Atropos, 'Inflexible,' who cuts it.
Campbell identifies Clotho as the originating spinner of the life-thread within the triadic Fate-goddess structure, and traces her symbolic influence into Norse and fairy-tale imagery of the spindle as destiny.
