Famous quotes containing the word hand:
“If you are ambitious of climbing up to the difficult, and in a manner inaccessible, summit of the Temple of Fame, your surest way is to leave on one hand the narrow path of Poetry, and follow the narrower track of Knight-Errantry, which in a trice may raise you to an imperial throne.”
—Miguel De Cervantes (1547–1616)
