‘Is there anybody there?’ said the Traveller,
Knocking on the moonlit door;
And his horse in the silence champed the grasses
Of the forest’s ferny floor:
And a bird flew up out of the turret,
Above the Traveller’s head:
And he smote upon the door again a second time;
‘Is there anybody there?’ he said.
But no one descended to the Traveller;”–Walter de la Mare (The Listeners)
