Blue Over The Kazan

See prayers written by Poul Anderson here, also Mary And Grass and Prayers.

"Then rest while you can, Kossara. Sleep comes not black, no, blue as a summer sky over the Kazan, blue as the cloak of Mary.... Pray for us now, and in the hour of our death."
-A Knight Of Ghosts And Shadows, X, p. 468.

O, men from the fields!
Come softly within.
Tread softly, softly,
O! men, coming in.

Mavourneen is going
From me and from you,
To Mary, the Mother,
Whose mantle is blue!

From reek of the smoke
And cold of the floor,
And peering of things
Across the half-door.

O men from the fields!
Soft, softly come thro'.
Mary puts round him
Her mantle of blue.
