—George Gordon Noel Byron (1788–1824)
“At painful times, when composition is impossible and reading is not enough, grammars and dictionaries are excellent for distraction.”
—Elizabeth Barrett Browning (1806–1861)
“The composition of a tragedy requires testicles.”
—Voltaire [François Marie Arouet] (1694–1778)
