That's the first line of the proem and complicated tells us nothing about the protagonist. Everyone can be complicated, but only Odysseus is πολύτροπον. It's a quality of character few people possess. I feel like Pope's line, despite the artistic license, kept that uniqueness.

My copy in Spanish says the man of many paths (hombre de muchos senderos).

"Complicated" seems trite, almost meaningless. Though I'm willing to read beyond the first line of their translation.

If it’s good enough for Shaft it’s good enough for this guy.
