Here's a painting I finished the about a week ago of Nótt, who is night personified. I have also included the initial thumbnail drawing for the completed painting.
Nott rides across the sky bringing the night with her hair and cape made of darkness and stars. Her skin is dark, and she rides her horse, Hrímfaxi, from whose mane the dew falls. In relation to the Norse godhead, she is actually Thor's grandmother. Day is personified in her son, Dagr.
I posted the sketch for this one a while ago, so I'm glad to finally share the final version of this one. I really enjoyed the horse on this one 'cause I love cool horses!
