Simargl (a dog with a body of a bird) is one of the most ancient creature of the Indo-Iranian mythology who lives on the tree of all seeds and who drops the seeds on the ground. Therefore they became a symbol of fertility. An image with a pair of Simargle also supports the idea of fertility. Another important function of Simargle was to be a mediator between the worlds and to rescue lost travelers.
The image of simargle depicted on this bracelet is taken from the painting on the South door of the Cathedral of Nativity in Suzdal (XIII century).
