Variations on a Theme of Laforgue

Youth as it opens out discloses
The sinister metempsychosis
Of lilies dead and turned to roses
Red as an angry dawn.
But lilies, remember, are grave-side flowers,
While slow bright rose-leaves sail
Adrift on the music of happiest hours;
And those lilies, cold and pale,
Hide fiery roses beneath the lawn
Of the young bride's parting veil.
