Welcome to my site! My name is Carl Olsen (aka C.G. Olsen, aka Calle). A few of the hats I wear include: Norse mythologist, poet, writer, watercolorist, illustrator, translator, editor, and blogger. I filed my dissertation on Viking poetry about pictures of myths on shields back in 2009 and since then have taught at UC Berkeley, UCLA, and Gustavus Adolphus College and have pursued various freelance jobs, including translating Heavenly Bodies, a large and erudite academic work by Swedish theologian Ola Sigurdson, and creating the chapter heading illustrations for the book Mathematics for Human Flourishing by Francis Su (out now!), along with publishing several poems and selling my artwork on Etsy and Redbubble.
