Pnyx
niks, a place of public assembly in ancient Athens. It occupied an open-air terrace leveled off on the slope of a hill, southwest of the Acropolis. In shape, it was a sector of a circle--to use a homely illustration, about two-fifths of a round pie--with the wide apex pointing toward the center of the hill. A semicircular retaining wall upheld the outer boundary. The apex was cut down about thirteen feet into the solid rock. A cube of rock left at the apex and ascended by three steps from either side served as a platform for public speakers. When Demosthenes or some other famous orator ascended the bema, as it was called, to address the populace, he faced a surging mass of humanity 212 feet deep, extending 197 feet to the right and left. The bema was originally the lowest point of the pnyx. During the centuries that have passed many of the huge stone blocks of the retaining wall have been removed or have slid down hill, giving the old arena an outward slope.

Podiebrad
GEORGE BOCZKO, King of Bohemia; born of a noble family in Podiebrad, April 6, 1420, and became an adherent of the moderate party of the Hussites. When the Catholic barons (1438) carried the election of Albert V. of Austria (II. of Germany), Podiebrad allied himself with the Utraquists in Tabor, who offered the sovereignty of Bohemia to Casimir, King of Poland. After forcing Albert to raise the siege of Tabor and retire to Prague, Podiebrad was recognized as the leader of the Utraquists; then he seized on Prague (1448), and got himself made governor or regent of Bohemia, from 1453 to 1457, for the young king Ladislaus. On the death of Ladislaus, Podiebrad was chosen his successor, and was crowned early in 1458. In 1462 he decided to uphold the terms of the compactata of Prague (1433); this angered the Pope, Pius II., and he was only prevented from excommunicating Podiebrad by the emperor. The next Pope, Paul II., did in 1466 promulgate against him the ban of excommunication. Matthias Corvinus of Hungary was the only prince who took the field to enforce but him Podiebrad surrounded at Wilamow (1469) and forced into a truce. Nevertheless Matthias was crowned king by the Catholic barons at Olmütz immediately afterward. Podiebrad died March 22, 1471.
