St. Lucia's wreath bread

It's about a girl saint from Scandinavia, this day is celebrated December 13, actually. But in my case- I just decided to make such a lovely bread, because of it's shape and serve it with Christmas holidays. It looks brilliant on a table with candles in it, it tastes great and is such a pleasure to the eyes, specially in the X'mas morning:)

1 cup milk
apr.70gr butter
100gr sugar
1 egg
2 packs yeast (20gr)
cardamom (or at least cinnamon and cloves) 1 t.s.
4 cups flour apr.
pinch of salt

First melt butter in milk with sugar on fire, set aside to cool a little. In a bowl mix flour (half of it), yeast, cardamom, then add 1 egg to the milk and pour into the dry ingredients. Mix well, adding more flour and then salt.
Knead for several minutes, cover the bowl with plastic and put away to rise for apr. an hour.

Now devide the dough into 2 parts (I used second part the next day, stored in the fridge). Roll out the dough into a sheet, and spread the filling.

Filling:
2 tb.s. butter (melted)
handful raisins
handful walnuts (cut and baked a bit)
cinnamon and sugar

First butter the dough, then sprinkle sugar, cinnamon, raisins and nuts.
Now roll it lengthwise, form a circle, seam and place on a baking sheet (covered with paper). Take scissors  and cut it all the way around, pulling each piece to the left and to the right. It looks like a wreath now. Cover with plastic and set for another 40 minutes aside.
Oven 175C. Brush the top with an egg and bake for 25-30 min (if getting too brown, cover with foil).
While it is still warm, make a glaze (sugar+melted butter+milk+vanilla) and sprinkle on top.
