Two doves upon the selfsame branch,

Two lilies on a single stem.

Two butterflies upon one flower:-

O happy they who look on them.

DIUIUIU

Who look upon them hand in hand

Flushed in the rosy summer light;

Who look upon them hand in hand

And never give a thought to night.

- "Song,"

Christina Rossetti
