Hár in Norse, Old pronounced as /ˈhɑːrː/, Jafnhár in Norse, Old pronounced as /ˈjɑvnˌhɑːrː/, and Þriði in Norse, Old pronounced as /ˈθriðe/ (anglicized as Thridi) are three men on thrones who appear in the Prose Edda in the Gylfaginning ("The Beguiling of Gylfi"), one of the oldest and most important sources on Norse mythology. Their names translate as High, Just-as-High, and Third in Old Norse, respectively. In the story, King Gylfi, calling himself Gangleri, engages in a test of wisdom with the three, asking them detailed questions about the Æsir, their deeds, and their future. The three respond until the final segment, in which the three men and the great hall suddenly disappear.
While the Gylfaginning never says so directly, some scholars believe the intent is that all three are manifestations of Odin, and thus would be able to answer Gangleri's questions in such detail, including ones on the eventual fate of the Æsir.
In the Gylfaginning, King Gylfi is travelling to Asgard, but the Æsir realize he is coming and prepare illusions (Norse, Old: sjónhverfing) for him. Gylfi finds a great hall and inquires as to its owner; he is told that the king owns the hall, and is offered a chance to meet him. Upon entering the throne room, he finds the three men:
The rest of the Gylfaginning then proceeds as a dialogue between Gangleri (Gylfi's pseudonym he has chosen) and the three men as they engage in something of a contest of wisdom; Gylfi asks detailed questions of the affairs of the Æsir, and the three respond with stories. At the very end, the three suddenly vanish along with the Hall. Gylfi returns to Sweden to tell tales of what he has learned.
A common assumption is that the three men are intended to be manifestations, aspects, disguises, or illusions controlled by Odin. Odin is both the wisest of the Æsir, and the king of the Æsir if the initial meeting at the illusory Great Hall saying Gangleri will be taken to the king is taken at face value. More directly, as Jesse Byock writes, all three names are mentioned in a list of names of Odin:[1]
Conversely, John Lindow argues that the three were probably not Odin, at least not in the view of Snorri Sturluson, compiler of the work. Lindow notes that "Gangleri" is also a name of Odin, but that neither side of the conversation or events quite matches another story of Odin. If Snorri was either responsible for or approved of the euhemerization account in the Prologue of the Prose Edda that conflates the Norse Æsir with Greco-Asian refugees from the fall of Troy, then the three may have merely been descendants of such a claimed migration in-setting.
The name Hár means 'High' or 'High One' in Old Norse and Icelandic; it may stem from an earlier Proto-Norse form *hauhaz.
The origin of the name Hárr remains unclear. A number of scholars, including Jan de Vries, E. O. G. Turville-Petre and Vladimir Orel, have proposed to translate it as 'One-eyed'. The word may derive from a Proto-Norse form reconstructed as *Haiha-hariz ('the One-eyed Hero'), itself a compound formed with the Proto-Germanic word *haihaz ('one-eyed'; cf. Gothic haihs 'one-eyed').[2] A Proto-Indo-European origin is also suggested by the Latin ('blind') and the Old Irish caech ('one-eyed'), with regular Germanic sound shift *k- > *h-. Alternatively, Hárr has been interpreted as meaning 'the hoary one', 'with grey hair and beard', or else as an adjectival form of the lexeme Hár ('High One').
A variant of Hár, Hávi ('the High One'), appears in the poem Hávamál ('Words of Hávi' / Songs of Hávi) as a name of Odin.
According to the catalogue in the Völuspá ('Prophecy of the Völva'), Hár is the name of a dwarf, presumably unrelated to Odin.
In the Skáldskaparmál, a quote from the Þórsdrápa (Thorsdrapa) appears to also refer to Thridi as a name of Odin, given that it would make sense for Thor to be departing from Asgard in the journey described to Jötunheimr that originates "from Third's":
Another short quote in the Skáldskaparmál refers to a "barley locked" or "pine-haired" wife of Thridi which seems to be a reference to the land itself, covered with plants:
