The richest body of Saule material is the cycle of dainos about a celestial family and its marriages. In these songs the Sun and the Moon are a married pair whose union fails; the divine twins, sons of Dievas, court the daughters of the Sun; the Morning Star Ausrine and the Evening Star lay Saule's path and light her fire. This is one of the fuller survivals anywhere of an Indo-European "sun-maiden" mythology, comparable to the Vedic Surya and the Greek Helios traditions, and it is unusual in making the sun feminine and the moon masculine. Saule is bound up with amber, the fossil resin of the Baltic coast: her tears are amber, and the material that made the region famous in antiquity is folded into her myth. Her turning points, the solstices, were marked by the great fire-festivals that survive as the Latvian Ligo and Lithuanian Rasa of midsummer.
A related strand of the daina cycle turns the wedding itself toward grief: when the thunder-god Perkunas splits a golden oak grown for her daughter's wedding procession, Saule spends years gathering the shattered pieces and trying, in vain, to make them grow again, weeping as they fail to take root. She weeps too for the zaltys, the grass snake once kept as a household guardian in Baltic farmsteads, and one telling makes this very grief the origin of amber, so that the region's characteristic stone becomes, in the songs, the visible trace of the goddess's own sorrow.
