In Norse* mythology, Freyja was the goddess of love and fertility, associated with affairs of the heart. According to one Norse source, "all lovers would do well to invoke her." Her identification with love and passion led other deities to condemn her behavior. The trickster god Loki claimed that Freyja was the lover of all of the gods and accused her of sleeping with her twin brother, Freyr, the god of fertility and prosperity.
One story about Freyja explained how she acquired her favorite possession, the Necklace of the Brisings, made by four dwarfs. She agreed to spend a night with each of the dwarfs in exchange for the necklace. However, Loki later crept into Sessrumnir, Freyja's heavenly home, while Freyja was sleeping and stole the precious necklace.
In addition to being concerned with matters of love, Freyja had links with death and the world of the dead. Half of all the warriors who died in battle were given to her; the other half went to Odin, ruler of the gods. Freyja was associated with Frigg, goddess of marriage. Some scholars have suggested that the two goddesses represent different aspects of the same deity, who oversaw both love and motherhood.
