I am not sure if this sculpture is called The Hermit or not, but it certainly reminded me of the Tarot card with the similar image of a hooded figure with a lantern.

(And Led Zeppelin too of course.)

I think in Tarot the image is supposed to signify a need to  withdraw from society in order to learn, but to return to the fold later and share the new knowledge. 

So it might make sense this sculpture was found at a port.
