It's beautifully written. I might nevertheless slightly disagree with the final meaning: in the French phrase, it is literally the action of touching the country that enchants him, not the country itself. Something like "touching this country with the bow of his boat couldn't fail to enchant him". To try to make myself clear, the quest may be more important than the Grail."once touched by the bow of his boat this country couldn't fail to enchant him"
