Famous quotes containing the words open and/or circuit:
“Why make so much of fragmentary blue
In here and there a bird, or butterfly,
Or flower, or wearing-stone, or open eye,
When heaven presents in sheets the solid hue?”
—Robert Frost (1874–1963)
“each new victim treads unfalteringly
The never altered circuit of his fate,
Bringing twelve peers as witness
Both to his starry rise and starry fall.”
