The question for the third day asks about symbols and icons of Loki. Because I’ve been musing about Loki as a sort of “Lord of Fractal Forces,” whose shapeshifting begins at subatomic levels and probably follows fractal-like patterns in the process, I’m going to answer this question about just a few of his symbols and iconic moments, using a selection of fractal images.
Please see references at bottom of this article.
Hail Flamehair! Loki as a sky-walking god of fire and lightening.  
Loki as Lóðurr (or Lóður) grants blood and “good color” to the first humans, Ask and Embla, who start out as trees (18th stanza Völuspá). 
Hail, Father of Monsters!
Loki, as father of Hel, Fenrir, and Jormungandr. 
Hail, Mother of Witches!
Mother of witches (troll women), after eating a burnt woman’s heart, left on a tree, possibly as an offering (see stanza 12, Völuspá hin skamma).
Hail, Mother of Sleipnir!
Loki gives birth to the magic, eight-legged horse, Sleipnir. [see 2 again.]
Hail to the Bound God! (Let’s get you out of there!)
Loki’s agony: bound with his child’s entrails, unable to escape the venom dripped from a snake. 
Hail Vulture’s Path!
Loki as Gammleið, “the vulture’s path” and perhaps a reference to cremation fire. 
Loki captains Naglfar, the corpse ship also known as the “Ship of Dead Men’s Nails,” prior to Ragnarok. (See stanza 51, Völuspá.)  
The Star Sirius, Lokabrenna (Loki’s Torch)
