Earendil a Man? Or Aragorn as King of Arnor?

Thank you, Sophia .

I wholeheartedly agree with your thoughts on the inclusion of Earendil in the line, personally. He seemed to me much more of a Man than an Elf, always, even after his fate had been decided. However, would the Professor have done this? - and for what reasons? Those questions really play on my mind, especially considering the ambiguity with Aragorn.

In a fashion I cannot help but believe that Tolkien deliberately made it appear so ambiguous; hinting at shades of the future, while leaving the impression of ages past. This would increase the wonder and suspense of the reader when later reading about Aragorn, having those hints at his future - while making also the tales of Earendil that much more wonderful when the reader comes to the Sil.
