National Twin Day - December 18

Twins, whether fraternal or identical, share everything from the start. Although their personalities may be different, they often know what the other is going to say before the words are spoken. Distance isn't an issue either. Twins are able to stay connected whether you live in the United States or around the world.

Of course, mythology teaches us about twins from the start, as does the Bible. We investigate a variety of human conditions from Esau and Jacob to Aphrodite's twin sons Phobos and Deimos to Aphrodite's Phobos and Deimos, as well as the constellation's mortal and immortal twins Gemini.

Notable twins

We've been fascinated by twins for the past several years, as well as the years. Literature embraced the twin duplicity with a zeal. Take Shakespeare's Twelfth Night, for example, and the confusing that ensues with Sebastian and Viola in the aftermath. When twins are depicted on modern-day sitcoms, we're in tears. Phoebe Buffay of the sitcom Friends and, more recently, Sheldon Cooper from The Big Bang Theory humbly portrayed their twin lives.
