Urðr is the Norn traditionally associated with the past.
The three principal Norns in Norse mythology are Urðr, Verðandi, and Skuld. In the familiar interpretation, Urðr represents what has happened, Verðandi what is happening, and Skuld what is yet to come. They are linked with fate and are often described as shaping or determining the destinies of gods and humans.
Urðr’s name is related to the Old Norse verb verða, “to become,” and is commonly interpreted as “that which became” or “what has happened.” The English word “wyrd,” meaning fate in Old English tradition, is an etymological relative, although the two terms should not be treated as perfectly identical in meaning.
The past-present-future interpretation is a useful modern shorthand, but scholars caution that the surviving Old Norse sources do not always present the Norns as a neat chronological trio. Their names can express aspects of fate rather than three strictly separate time periods. That nuance does not change Urðr’s standard quiz association with the past.
