Caption: "The Wolves Pursuing Sol and Mani (the title given to the work in the list of illustrations on page vii of the source)." (Slightly edited.)
In Norse mythology, Sun goddess Sol is pursued by the wolf Skoell and Moon god Mani is pursued by the wolf Hati Hrothvitnisson.
Skoell and Hati Hrothvitnisson are evidently invisible.
