Interesting parallel
 

Can't claim it, it's Thomas Honneger's observation, but I like it: Turin's return to Dor-Lomin as a subversion of Odysseus' return to Ithaca.

There's more classical influence in Tolkien than many realize

Definitely a subversion. Other than murdering the usurper Brodda, everyone Turin loved was already long gone, and he didn't stay in Dor-Lomin to resume mastery of the land, but fled as a fugitive and murderer. No happy endings like good ol' Odysseus. Not even a venerable dog to greet him.

But an aged servant (the only one to recognize him)

You could add a kinswoman forced to marry an intruder, a marriage that the returning hero tries to disrupt. Except with very different outcomes.
