The triple spiral or triskele is a Celtic and pre-Celtic symbol found on Irish Mesolithic and Neolithic sites. It represents the "three realms:" land, water, and sky. The triple spiral may also represent the nine-month period of pregnancy, since the sun takes a fourth of a year to go from the celestial equator (an equinox) to extreme north or south declination (a solstice), and vice versa. During each three-month period, the sun's path across the sky appears to form a closely wound quasi-helical shape, which can be likened to a spiral, so that three spirals could represent nine months, providing an explanation for a link between fertility and the triple-spiral symbol.
It can also represent the Triple Goddess: Mother, Maiden, and Crone. These two motifs, pregnancy, infant, and motherhood, are married to form one mandala.
