A Worm, A Dog, Something Big And A Giant

Poul Anderson, The Broken Sword (London, 1977), Chapter XXII.

Entering Jotunheim, Skafloc and Mananaan must fight their way past:

a great white worm;
a great red dog;
"...something big and heavy..." of unknown shape in the dark. (p. 162)

Then they meet Bolverk the Jotun:

so tall that his head is almost invisible in the gloom;
so broad that, despite his height, he is squat;
covered in hair;
wearing only a dragonskin apron;
gnarled like an old tree;
"...muscled like a snakepit..." (ibid.);
with matted black hair and beard hanging to his waist;
short-legged;
lame in one leg;
hunch-backed;
bent forward so that his arms touch the ground;
broad-nosed;
wide-mouthed;
face scarred and seamed;
with empty eye sockets;
voice booming and hissing like the rivers of hell -

- and I wish I hadn't started that description.
