Among the Norse, the god Balder is the most closely associated with the solstices. In a myth that explains the actions of the midsummer and midwinter Sun, Balder, the son of the god Odin, was said to die at the hands of his evil brother, who wielded a mistletoe stake each summer solstice. He was reborn at the winter solstice, or what is still known in Germany as Mother Night (the 'mother' in question being the goddess who brings the new born Sun back into existence).

What he does not mention is that Balder is the Norse counterpart of Helios (the Greek forerunner of Sol); he was the god of light, son of Odin and Frigg, as Helios was the son of Hyperion and Theia.
