Freyr (sometimes anglicized Frey) is one of the most important gods of Norse paganism. Freyr was highly associated with agriculture, weather and, as a phallic fertility god, Freyr "bestows peace and pleasure on mortals". Freyr, sometimes referred to as Yngvi-Freyr, was especially associated with Sweden and seen as an ancestor of the Swedish royal house.
