The goddess of the week is the lovely Freya, goddess of love from the Norse pantheon.
From the D'Aulaires "Book of Norse Myths":
"Freya was the goddess of love. She came to Asgard in a carriage drawn by gray cats with her little daughter Noss on her lap. Noss was so sweet that her name is used to describe anything delightful.
Freya, most beautiful of the godesses, was often sad, for her husband Od had disappeared. He was a wanderer and a dreamer and had been lost in one world or another. Freya often went looking for him. Sometimes she drove off with her cats and sometimes she flew off as a falcon, for she had a suit of falcon feathers which carried her swiftly through the air when she put it on.
The Aesir built a hall for Freya in Asgard which was almost as big as Odin's . It had to be so big because Freya was very fond of company, and her hall was always thronged with merry men.
Still, Freya would often think of her lost husband and weep herself to sleep. But she was lovely even when she wept, for her tears, rolling silently down her round cheeks, were pure drops of gold."
Freya also owned Hildesvini, Battle Boar, a great swine that she would ride when not using her chariot. He was actually one of her human lovers in disguise.
The Norse said that the Milky Way was Freya's necklace.
