Literary captain described as a "grand, ungodly, god-like man" (4)
I believe the answer is:
ahab
(Other definitions for ahab that I've seen before include "Fictional whaler" , "One whose nemesis was white" , "Jezebel's husband or captain in 'Moby Dick'" , "Melville's whale chaser" , "Jezebel's husband, wicked king in the 'Old testament'" .)
