Historia de omnibus Gothorum Sueonumque regibus
The Historia de omnibus Gothorum Sueonumque regibus (History of all the kings of the Geats and the Swedes) is a posthumously published, partly pseudo-historical work by Johannes Magnus, Sweden's last Catholic archbishop. In 1554 (ten years after his death), it was published in Latin by his brother Olaus Magnus.
