A high-ranking military commander, he seized the throne with the help of Arab armies who hoped to subjugate the Byzantine Empire. He then successfully defended Constantinople against the Arabs (717-718). Having crowned his son Constantine V coemperor (720), Leo used his son's marriage to cement an alliance with the Khazars. Victory over the Arabs at Akroïnos (740) was crucial in preventing their conquest of Asia Minor. Leo issued an important legal code, the Ecloga (726). His policy of iconoclasm (730), which banned the use of sacred images in churches, engendered a century of conflict within the empire and further strained relations with the pope in Rome. orig. Vincenzo Gioacchino Pecci born March 2, 1810, Carpineto Romano, Papal States died July 20, 1903, Rome Pope (1878-1903). Born into the Italian nobility, he was ordained a priest in 1837 and entered the diplomatic service of the Papal States. He was appointed bishop of Perugia in 1846 and was named a cardinal in 1853. He was elected pope in 1878, and, despite his advanced age and frail health, he directed the church for a quarter of a century. Like his predecessor, Pius IX, he opposed Freemasonry and secular liberalism, but he brought a new spirit to the papacy by adopting a conciliatory attitude toward civil governments and taking a more positive view of scientific progress. orig. Giovanni de' Medici born Dec. 1, 1475, Florence died Dec. 1, 1521, Rome Pope (1513-21), one of the most extravagant of the Renaissance pontiffs. The second son of Lorenzo de' Medici, he was educated at his father's court in Florence and at the University of Pisa. He was named a cardinal in 1492, and in 1494 he was exiled from Florence by the revolt of Girolamo Savonarola. He returned in 1500 and soon consolidated Medici control of the city. As pope, he became a patron of the arts, accelerating construction of St. Peter's Basilica. He strengthened the papacy's political power in Europe, but his lavish spending depleted his treasury. He discouraged reforms at the fifth Lateran Council, and he responded inadequately to the Reformation, excommunicating Martin Luther in 1521 and failing to address the need for change, a lapse that signaled the end of the unified Western church.

Leo Tolstoy: Russian Lev Nikolayevich, Count Tolstoy born Sept. 9, 1828, Yasnaya Polyana, Tula province, Russian Empire died Nov. 20, 1910, Astapovo, Ryazan province Russian writer, one of the world's greatest novelists. The scion of prominent aristocrats, Tolstoy spent much of his life at his family estate of Yasnaya Polyana. After a somewhat dissolute youth, he served in the army and traveled in Europe before returning home and starting a school for peasant children. He was already known as a brilliant writer for the short stories in Sevastopol Sketches (1855-56) and the novel The Cossacks (1863) when War and Peace (1865-69) established him as Russia's preeminent novelist. Set during the Napoleonic Wars, it examines the lives of a large group of characters, centring on the partly autobiographical figure of the spiritually questing Pierre. Its structure, with its flawless placement of complex characters in a turbulent historical setting, is regarded as one of the great technical achievements in the history of the Western novel. His other great novel, Anna Karenina (1875-77), focuses on an aristocratic woman who deserts her husband for a lover and on the search for meaning by another autobiographical character, Levin. After its publication Tolstoy underwent a spiritual crisis and turned to a form of Christian anarchism. Advocating simplicity and nonviolence, he devoted himself to social reform. His later works include The Death of Ivan Ilich (1886), often considered the greatest novella in Russian literature, and What Is Art? (1898), which condemns fashionable aestheticism and celebrates art's moral and religious functions. He lived like a peasant on his great estate, practicing a radical asceticism. Finding his marriage unbearable, he departed suddenly for the local railway station, where he contracted a fatal pneumonia in the cold
