Strict solar alignment of Bronze Age rock carvings in SE Sweden

The Järrestad rock carving site in SE Sweden from the Bronze Age is examined as to the orientation of the individual carvings. A very strict orientation with respect to the main stages in the annual rhythm of the Sun is recorded; 60 feet, 61 shoes and a leading dancer all face the sunrise at Winter solstice, 20 ships face the sunset at Winter solstice, 12 feet point to the sunset at Summer solstice, and one serpent wiggles towards the sunrise at Summer solstice. Obviously, the Bronze Age people kept a strict control of the Sun's annual motions. The sunrise at Winter solstice seems to have been especially important.
