Runic prayer to Jord and Thor from 10th or 11th century

The Kvinneby amulet was dug up in Sweden and is dated to the 10th or 11th century. It is an amulet with 143 runic inscriptions that translate as a solemn prayer to the Earth Goddess, referred to as 'Erka', 'Fold' and 'Undirgoð' (the god beneath) and her 'single son' Thor.

I here to Erka, the undergod of the world,

for me, Bófi, to save myself.

Earth, I am known to thee!

And may the lightning raiser help evil from Bófi.

May Þórr protect him with the hammer that smashes Ámr.

Go the sea, Ámr! Flee,

foul ill-wight! Get nothing from Bófi.

Gods are under him and over him.
