How Uniform Was the Old Norse Religion?
II. Old Norse Myth and Society HOW UNIFORM WAS THE OLD NORSE RELIGION? Stefan Brink ne often gets the impression from handbooks on Old Norse culture and religion that the pagan religion that was supposed to have been in Oexistence all over pre-Christian Scandinavia and Iceland was rather homogeneous. Due to the lack of written sources, it becomes difficult to say whether the ‘religion’ — or rather mythology, eschatology, and cult practice, which medieval sources refer to as forn siðr (‘ancient custom’) — changed over time. For obvious reasons, it is very difficult to identify a ‘pure’ Old Norse religion, uncorroded by Christianity since Scandinavia did not exist in a cultural vacuum.1 What we read in the handbooks is based almost entirely on Snorri Sturluson’s representation and interpretation in his Edda of the pre-Christian religion of Iceland, together with the ambiguous mythical and eschatological world we find represented in the Poetic Edda and in the filtered form Saxo Grammaticus presents in his Gesta Danorum. This stance is more or less presented without reflection in early scholarship, but the bias of the foundation is more readily acknowledged in more recent works.2 In the textual sources we find a considerable pantheon of gods and goddesses — Þórr, Óðinn, Freyr, Baldr, Loki, Njo3rðr, Týr, Heimdallr, Ullr, Bragi, Freyja, Frigg, Gefjon, Iðunn, et cetera — and euhemerized stories of how the gods acted and were characterized as individuals and as a collective. Since the sources are Old Icelandic (Saxo’s work appears to have been built on the same sources) one might assume that this religious world was purely Old 1 See the discussion in Gro Steinsland, Norrøn religion: Myter, riter, samfunn (Oslo: Pax, 2005).

9. Freyr's Solar Power and the Purifying Sword
The Waning Sword E Conversion Imagery and Celestial Myth in Beowulf DWARD The Waning Sword Conversion Imagery and EDWARD PETTIT P The image of a giant sword mel� ng stands at the structural and thema� c heart of the Old ETTIT Celestial Myth in Beowulf English heroic poem Beowulf. This me� culously researched book inves� gates the nature and signifi cance of this golden-hilted weapon and its likely rela� ves within Beowulf and beyond, drawing on the fi elds of Old English and Old Norse language and literature, liturgy, archaeology, astronomy, folklore and compara� ve mythology. In Part I, Pe� t explores the complex of connota� ons surrounding this image (from icicles to candles and crosses) by examining a range of medieval sources, and argues that the giant sword may func� on as a visual mo� f in which pre-Chris� an Germanic concepts and prominent Chris� an symbols coalesce. In Part II, Pe� t inves� gates the broader Germanic background to this image, especially in rela� on to the god Ing/Yngvi-Freyr, and explores the capacity of myths to recur and endure across � me. Drawing on an eclec� c range of narra� ve and linguis� c evidence from Northern European texts, and on archaeological discoveries, Pe� t suggests that the T image of the giant sword, and the characters and events associated with it, may refl ect HE an elemental struggle between the sun and the moon, ar� culated through an underlying W myth about the the� and repossession of sunlight. ANING The Waning Sword: Conversion Imagery and Celesti al Myth in Beowulf is a welcome contribu� on to the overlapping fi elds of Beowulf-scholarship, Old Norse-Icelandic literature and Germanic philology.

On Freyr—The 'Lord' Or 'The Fertile One'? Some Comments on the Discussion of Etymology from the Historian of Religions
On Freyr—the ‘Lord’ or ‘the fertile one’? Some comments on the discussion of etymology from the historian of religions’ point of view1 Olof SUNDQVIST Introduction Ever since the beginning of modern research in the 19th century, histo- rians of religions have used gods’ names, and the etymologies that can be associated with them, as a method to determine and distinguish the various mythical beings, their nature and functions. Also the Old Norse deities have been interpreted by means of their names. In the present paper focus will be put on the ancient Scandinavian deity Freyr. His name has been a matter of debate in recent research, especially among philologists and specialists on names (onomasticians). Their arguments have, however, not always been based on linguistic arguments exclu- sively, but also on knowledge brought from the history of religions. Since some of the theories on Freyr in the history of religions are dis- puted, it is important that such aspects are brought to light also for the researchers in onomastics. A paradox may be discerned in research today. A new etymology of the god’s name has been suggested. This etymology has support from previous interpretations of the god Freyr made by historians of religions working in the mid 20th century. While a new and more nuanced image of Freyr, produced by historians of religions around 1995-2015, can find support from the old etymology. Freyr and the etymology of his name There has almost been consensus that Freyr’s name should be con- ceived as a Proto-Nordic *Fraujaz (derived from the Indo-European 1 During the preparation of this article some individuals have given me important advices, answered questions and discussed some problems related to linguistic aspects.

The Divine Appearance of Härn
The divine appearance of Härn THE DIVINE APPEARANCE OF HÄRN Determining the identity of a Bronze Age metal hoard Magdalena This article aims to investigate the mysterious divinity Härn on the basis of a Bronze Age metal hoard from Forsgren Härnevi in Uppland. The premise is that this hoard rep- resents a cultural category that reflects a divine concept that must be investigated in order to understand the meaning behind the deposition. Through mythological parallels, Härn’s characteristics will be explored as well as the relation between the sun and fertility across time and space. It is suggested that Härn originally was a sun goddess emanating from the Bronze Age and related to the Norse goddesses Njärd and Freyja. Key words: Härnevi, metal hoard, Bronze Age, com- parative mythology, folklore, sun, fertility INTRODUCTION How is it possible to obtain knowledge about the characteristics of an unknown divinity such as Härn who only occurs in a few Swedish place names? The name Härnevi had attracted interest for a long time (Grau 1754; Ekblom 1872), but it was not until Hans Hildebrand (1899:6) drew attention to the sacral meaning of the second part of the place name that discussions started as to which divinity *Härn referred to; compound place names with -vi are usually theophoric. Magnus Olsen suggested in 1908 that Härn was related to one of Freyja’s second names, Hørn, mentioned in Snorre’s Edda. Nevertheless, it was Hans Sperber’s (1912) suggestion that Härn is derived from an old word for Current Swedish Archaeology, Vol 18, 2010 105 Magdalena Forsgren flax which drew the greatest support.
