Cross-Dressing

Loki said:
24 ‘But you, they say, practised seid on Samsey,*
and you beat on the drum as seeresses do,
in the likeness of a wizard you journeyed over mankind,
and that I thought the hallmark of a pervert.’


- Poetic Edda, Lokasenna


("seid on Samsey: the use of drums and cross-dressing seems to be typical of seid, a type of magic said to be practised by the Vanir, especially Freyia (Seeress’s Prophecy, v. 23), and by the Lapps." - from the Explanatory Notes section included with the translation)

----------

33 ‘All the seeresses are descended from Vidolf,
all the wizards from Vilmeid,
and the seid-practisers from Svarthofdi,*
all the giants come from Ymir.


- Poetic Edda, Hyndluliod


("seid-practisers: the particular form of shape-changing and cross-dressing magic associated with the Vanir." - from the Explanatory Notes section included with the translation)
