Worship of Frey
No weapons were ever admitted in Frey’s temples, the most celebrated of which were at Throndhjeim in Norway, and at Thvera in Iceland. In these temples oxen or horses were offered in sacrifice to him, a heavy gold ring being dipped in the victim’s blood ere the above-mentioned oath was solemnly taken upon it.
Frey’s statues, like those of all the other Northern divinities, were roughly hewn blocks of wood, and the last of these sacred images seems to have been destroyed by Olaf the Saint, who, as we have seen, forcibly converted many of his subjects. Besides being god of sunshine, fruitfulness, peace, and prosperity, Frey was considered the patron of horses and horsemen, and the deliverer of all captives.
“Frey is the best
Of all the chiefs
Among the gods.
He causes not tears
To maids or mothers:
His desire is to loosen the fetters
Of those enchained.”
Norse Mythology (R. B. Anderson).
