An accusing stare. That's why the creature is so unnerving.
So much goes into drawing! You put all this fascinating thought into your works, too. Then I go looking up stuff to better understand. Nice pre-coffee fare, your posts. This morning I found these:
Moreover, the valknut is said to often accompany symbols and possibly depictions of the god Odin, whose roles in Norse mythology include ferrying the dead to the afterlife.
Mimir was sent by the Aesir as a hostage to the rival gods (the Vanir), but he was decapitated and his head was returned to the Aesir. The god Odin preserved the head in herbs and gained knowledge from it. According to another story, Mimir resided by a well that stood beneath one of the roots of Yggdrasill, the world tree.
In Norse mythology, Yggdrasill is an enormous ash tree that connects the nine worlds, including the underworld (Niflheim), the earth (Midgard), and the realm of the gods (Asgard). Yggdrasill is associated with both life and death: it acts as a gallows that the god Odin hangs himself from in order to gain mystical knowledge, and it is said to be the source of new life after Ragnarök (Doomsday), the catastrophic final war of the gods.
I gotta go make some coffee. Thanks for the trip into Norse mythology. Everything I do know about it, has come to me through you.
