It is very interesting that this image is often used in art. There are exactly three of them, since these are three specific archetypes: youth, motherhood and old age. Where also the first is love and emotions, the second is birth and fertility, and the third is loneliness and wisdom. I personally liked the witches from the Witcher, as well as the legends full of such images, Greek Moira, triune goddesses in Hinduism, Hecate.
