Famous quotes containing the words registered and/or designs:
“Let fame, that all hunt after in their lives,
Live registered upon our brazen tombs,
And then grace us in the disgrace of death;
When spite of cormorant devouring Time,
Th’ endeavor of this present breath may buy
That honor which shall bate his scythe’s keen edge,
And make us heirs of all eternity.”
—William Shakespeare (1564–1616)
“My own thoughts
Are my companions; my designs and labors
And aspirations are my only friends.”
—Henry Wadsworth Longfellow (1807–1882)
