Niflheim was colder than cold, and the murky mist that cloaked everything hung heavily. The skies were hidden by mist and the ground was clouded by the chilly fog.
After these came the Periphallia, a troop of men who carried long poles with Phalli hung at the end of them; they were crowned with violets and ivy, and they walked repeating obscene songs. These men were called Phallophori; these must not be confounded with the Ithyphalli, who, in indecent dresses and sometimes in women’s costume, with garlanded heads and hands full of flowers, and pretending to be drunk, wore at their waist-bands monstrous Phalli made of wood or leather; among the Ithyphalli also must be counted those who assumed the costume of Pan or the Satyrs. There were other persons, called Lychnophori, who had care of the mystic winnowing-fan, an emblem whose presence was held indispensable in these kinds of festivals. Hence the epithet ‘Lychnite’, given to Bacchus.
