Ullr was one of the deities who watched over the sanctity of oaths. Traditionally his oaths were made on a ring, which was then buried in front of his shrine. This ritual is for any kind of oath that you feel would do better with a divine witness. However, remember that if you ask a deity to be a witness to your oath, you then give them the right to make sure that you keep that oath, by any means necessary. If you get them involved, they stay involved. Because of this, please don’t do this lightly. Think about the oath for a long time before you jump in. Make sure that it is something you can keep without terrible damage to your life or that of your loved ones – or future loved ones.

Ullr’s oaths were publicly made in front of his shrine, so you will want human witnesses as well. If it is an oath to another person, they should be there also. Buy a ring that seems appropriate to you. It does not have to fit any of your fingers perfectly; it need only be large enough to slip over the first joint of at least one finger. Bring along also three pieces of thread – one black, one white, and one forest green. Twist them together into one thread.

Since we no longer have public Ullr shrines, you will need to make one. It’s not hard – drape a table or box in colors of evergreen, snow, and black. You might lay out a bow and arrows, a pair of skis and/or skates, small figures of deer, skis, sleds, snowflakes (there are Christmas ornaments of all of those out there), evergreen boughs (yew if you can get it), and perhaps a cup or bowl to pour a libation out of. Get him something for a libation and perhaps a food offering. Ideally it should be set up outside, in a forest of some sort, a place where

Everyone should gather in front of Ullr’s altar. Open the rite by reciting the following prayer:

Hunter who smells out every lie

And every broken word,

Swift as an arrow strike,

Swift as the arrow of truth,

We ask you, Lord of the Hunt,

Implacable as winter ice,

Hear this oath taken in your presence

And guard it well, with swift

And thorough justice should it be

Knowingly broken and cast aside.

Hail Ullr, Lord of Winter,

May you look with your glance of honor

Upon all of us here.

The first person to make the oath then picks up the ring and places it on his finger, saying, “What goes out, comes back around, as winter follows summer.” They then speak their oath aloud to all present.

If a second person is making the oath – if, for example, they are making oaths to each other – then they take the ring from the first person and place it on their finger, also saying, “What goes out, comes back around, as winter follows summer.” Then the ring is removed, and the twisted thread is wrapped around it and tied with three knots. If there is more than one oath-taker, they share the knotting.

Then a hole is dug in the earth and the ring is placed in it. The oath-taker(s) may have help with the digging, but they must cover the ring with earth themselves. Then the rite is closed with the following prayer:

Hail Ullr, Lord of Winter,

Which follows summer

In the great circle of justice and honor.

May you watch over us

With eyes of ice and iron,

With steady hand on the still-bent bow.
