So is she a sail-less ship with a Silmaril on the silver mast-top, and Earendil flitting around it on wings? Or does Vingilot have a sail (ALL art of Vingilot shows at least one sail) and Earendil wingless standing on the foredeck with a Silmaril upon his brow (but possibly Elwing flitting around on wings) ?
Is this Bilbo getting things wrong again? ( I'm visualising Elrond being quietly amused, both at Bilbo, and also at Aragorn suffering agonies of Mortal Embarrassment on Bilbo's behalf, while Bilbo is quite oblivious.)
