As a "divine" or "angelic" person Varda / Elbereth could be said to be "looking afar from heaven" (as in Sam's invocation); hence the use of a present participle. She was often thought of, or depicted, as standing on a great height looking towards Middle-earth, with eyes that penetrated the shadows, and listening to the cries for aid of Elves (and Men) in peril or grief. Frodo (Vol. I, p. 208) and Sam both invoke her in moments of extreme peril. The Elves sing hymns to her. (These and other references to religion in The Lord of the Rings are frequently overlooked.)
Sinon, ton (1) et (2) feraient une belle ébauche de plan.
Et pour rebondir sur ta remarque, peut-on dire d'après le passage ci-dessus qu'il y a effectivement une communication à travers ces chants (la louange a Elbereth chez Elrond, la prière de Sam sur le même modèle)?
