I was talking to Andrea today about the fact that you have to do some research about Numerology. I decided to help you out a bit, and give you a short introduction about the 'magic number', 3.
You will find that there are several references to special nubers in literature and folklore. Most of these derive from the recurrent allusions to certain numbers, ranging from Ancient Greece to various religions. In addition, many philosophical or scientific themes or concepts come in threes.
Here are some examples from The Book of Threes:
In Greek mythology, the number three is is associated with different trios. The clearest example is how the universe was ruled by three gods - Zeus ruled the sky, Poseidon the seas and Hades the underworld. The Three Graces were daughters of Zeus- Euphrosyne, Aglalia, Thalia. The Three Fates were three sisters who decided the fate of men and gods - Clotho, Lachesis, Atropos. The three Furies were feared goddesses - Alecto, Tisiphone, and Megaera. There were also three Cyclopes, representing thunder, lighting, and the lighting bolt - Brontes, Steropes, and Arges. There are also creatures for which the number three is significant: The Chimaera has three heads - lion, goat, and snake; or the Cerberus, a three headed dog with a snake tail and snake heads protruding from his back.
In other cultures, we can find different examples. In Asian folklore there are three wise monkeys - Mazaru: Speak no evil, Mizaru: See no evil, Mikazaru: Hear no evil. In Norse Mythology, the world had three levels, and the world tree had 3 main roots going to each level. In Muslim legends, the Genie can grant three wishes. Even in children's folk tales, we can think about the 'Three Little Pigs' or 'Goldilocks and the Three Bears'.
Many examples come from religion. In Christianity, many concepts are tripartite: The Holy Trinity - Father, Son and Holy Spirit; the three temptations of Christ; the Holy Family - Mary, Joseph and Jesus. In Islamism, there are thre Holy Cities - Mecca, Medina, Jerusalem. In Hinduism, there is the Trimurti - Brahma the Creator, Vishnu the Preserver, and Shiva the Destroyer. In Buddhism, there is the Triple Gem - Buddha, Dharma, Sangha. In Judaism, there are Three Patriarchs - Abraham, Isaac, Jacob. And the list goes on...
Nowadays, we still have some supperstitions connected to the number three: 'third time's lucky', 'third time's a charm', 'the third man gets caught' or 'three strikes and you're out'.
