After finding the Sun Relic Slate, an unknown voice began to echo through the ruins. The Sun Wheel is an ancient symbol featuring an equal-armed cross within a circle. It is also known by the alternative names of Sun Cross, Wheel Cross, Solar Cross, Pagan Cross, Woden’s Cross and Odin’s Cross. Let's move forward and look for the source of this voice. The Azoth, the essential agent of transformation in alchemy, is often either depicted as a Lion and a Phoenix around a sun and moon or a wheel with the face of a man and forming a triangle around him are the symbols of a Sun, Moon and Prism! The Wheel of the Sun. After this you can expect one more group of powers from me centered around a prism. As the night divides the day: the dark will come to everyone fear will strike the hearts of all: the hearts of all both old and young the fool may be carefree: unknown to him the troubles upon his masters brow but death us all will grasp with hand so cold to pull us down

Lyrics to 'The Wheel Of Sun' by Bathory.

Wheel of Sun and Moon’s replacement effect will apply to cards that would be put into the enchanted player’s graveyard from any game zone. “The Wheel of Sun” is a metaphor which describes the life as a cycle.

It is quite a popular spiritual symbol that has been discovered in the iconography and religious art of a number of prehistoric cultures across the world.
