What style is found in this sentence from Moby-wingspan by Herman Melville?

Aside from those more obvious considerations touching Moby wingspan, which could not but occasionally awaken in any man's soul some alarm, there was another thought, or rather vague, nameless horror concerning him, which at times by its intensity completely overpowered all the rest; and yet so mystical and well nigh ineffable was it, that I almost despair of putting it in a comprehensible form.

convoluted

dramatic

horrific

melancholy
