Yes, the very common divine twins myths are believed to trace back to a shared Proto-Indo-European narrative. The central motif involves two twins born of the sky deity (or sun), with some customary attributes such as being horsemen or riding horse-drawn chariots.
Another manifestation of the binary conception of society and the world is the cult of twins widespread in Indo-European mythology. A myth of divine twins who are children of the sun god goes back to Proto-Indo-European antiquity. The myth is found in all the main ancient Indo-European traditions, which not only repeat the same motfisbut also share correspondences in the names of the heroes, thus establishing the Proto-Indo-European character of the motif and the personages.

A variant of this myth is found in all major Indo-European traditions. Furthermore, elements of this myth is preserved in the dual kingships widespread in antiquity, including Sparta, Rome, and some Germanic tribes. The popularity of the motif in Indo-European cultures allows scholars to securely reconstruct this as a common Proto-Indo-European heritage.
