The Barbarian Invasions (and a Challenge)

Just watched a rather stunning double-feature of movies tonight. The Canadian instant classic "Les Invasions Barbares" and Eastwood's "Mystic River". I may be the last person to see either of these beauties, but if by some chance you have missed either, rush to the videostore. One blogging postscript, and challenge of sorts. In a dinner near the end of "Invasions", one of the characters claims that "intelligence is not an individual trait, but is a collective phenomenon, national and intermittant." Three separate examples are then raised: 1. Athens, 416BC - Euripides premieres his Electra. Two rivals attend, Sophocles and Aristophanes, and two friends, Socrates and Plato. 2. Firenze, 1504 - Palazzo Vecchio, on facing walls, two painters: on the right, Leonardo da Vinci. On the left, Michaelangelo. An apprentice, Raffaello. A manager, Machiavelli. 3. Philadelphia, 1776-1787 - Declaration of Independence and the Constitution of the United States of America. Adams, Franklin, Jefferson, Washington, Hamilton, and Madison. The challenge? More examples. It is late so I am going to reflect and see what we can come up with in the comments. Creativity shall be awarded bonus points.
