I made a truce last night with Sorrow,
The queen of tears, the foe of sleep,
To keep her tents until the morrow,
Nor send such dreams to make me weep.

Before the lusty day was springing,
Before the tired moon was set,
I dreamed I heard my dead love singing,
And when I woke my eyes were wet.

Robert Fuller Murray
