Famous quotes containing the words ancient, medieval and/or era:
“Therefore it was surprising that, as we kept the newspapers from

Murmuring, in her sleep as it seemed, the ancient slogan
Noblesse oblige.”
—Josephine Miles (1911–1985)
“Nothing in medieval dress distinguished the child from the adult. In the seventeenth century, however, the child, or at least the child of quality, whether noble or middle-class, ceased to be dressed like the grown-up. This is the essential point: henceforth he had an outfit reserved for his age group, which set him apart from the adults. These can be seen from the first glance at any of the numerous child portraits painted at the beginning of the seventeenth century.”
—Philippe Ariés (20th century)
“How many a man has dated a new era in his life from the reading of a book.”
—Henry David Thoreau (1817–1862)
