(I did this last year, and will reprise it now, as the fic I had thought about posting didn't want to cooperate. Also, I know the date is by Shire reckoning, not Steward's reckoning, but I always realize too late that I've missed the 'proper' date.)
Through Rohan over fen and field where the long grass grows
The West Wind comes walking, and about the walls it goes.
'What news from the West, O wandering wind, do you bring to me tonight?
Have you seen Boromir the Tall by moon or by starlight?'
'I saw him ride over seven streams, over waters wide and grey;
I saw him walk in empty lands, until he passed away
Into the shadows of the North. I saw him then no more.
The North Wind may have heard the horn of the son of Denethor.'
'O Boromir! From the high walls westward I looked afar,
But you came not from the empty lands where no men are.'
From the mouths of the Sea the South Wind flies, from the sandhills and the stones;
The wailing of the gulls it bears, and at the gate it moans.
'What news from the South, O sighing wind, do you bring to me at eve?
Where now is Boromir the Fair? He tarries and I grieve.'
'Ask not of me where he doth dwell-so many bones there lie
On the white shores and the dark shores under the stormy sky;
So many have passed down Anduin to find the flowing Sea.
Ask of the North Wind news of them the North Wind sends to me!'
'O Boromir! Beyond the gate the seaward road runs south,
But you came not with the wailing gulls from the grey sea's mouth.'
From the Gate of Kings the North Wind rides, and past the roaring falls;
And clear and cold about the tower its loud horn calls.
'What news from the North, O mighty wind, do you bring to me today?
What news of Boromir the Bold? For he is long away.'
'Beneath Amon Hen I heard his cry. There many foes he fought.
His cloven shield, his broken sword, they to the water brought.
His head so proud, his face so fair, his limbs they laid to rest;
And Rauros, golden Rauros-falls, bore him upon its breast.'
'O Boromir! The Tower of Guard shall ever northward gaze
To Rauros, golden Rauros-falls, until the end of days.'
(Lament for Boromir, from The Two Towers, book three, chapter 1: "The Departure of Boromir".)
'A broken sword was on his knee. I saw many wounds on him. It was Boromir, my brother, dead. I knew his gear, his sword, his beloved face. One thing only I missed: his horn. One thing only I knew not: a fair belt, as it were of linked golden leaves, about his waist. Boromir! I cried. Where is thy horn? Whither goest thou? O Boromir! But he was gone. The boat turned into the stream and passed glimmering on into the night. Dreamlike it was. and yet no dream, for there was no waking. And I do not doubt that he is dead and has passed down the River to the Sea.'
(Faramir, from The Two Towers, book four, chapter 5: "The Window On the West".)
