High, Just-as-High, and Third

Hár [ˈhɑːrː], Jafnhár [ˈjɑvnˌhɑːrː], and Þriði [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.
