Famous quotes containing the word heart:
“The winds on the wold
And the night is a-cold,
And Thames runs chill
Twixt mead and hill.
But kind and dear
Is the old house here
And my heart is warm
Midst winters harm.”
—William Morris (18341896)

Is comelier than candles at Mother Marys feet.”

“Fasten your hair with a golden pin,
And bind up every wandering tress;
I bade my heart build these poor rhymes:
It worked at them, day out, day in,
Building a sorrowful loveliness
Out of the battles of old times.”
