[Petchora], the largest river in Northern Russia, rises in the Ural Mountains and flows N. through Vologda and Archangel, then westward and N. again, entering the Arctic Ocean by a large, island-studded estuary, after a course of 1000 m. through sombre forests and wild, sombre scenery.

[Peter, the Apostle], originally called Simon, was a fisherman on the Sea of Galilee; one of the first called by Christ to become a disciple; the first to recognise, as the foundation-stone of the Church, the divinity in the humanity of His Master, and the first thereafter to recognise and proclaim that divinity as glorified in the cross, to whom in recognising which, especially the former, was committed the keys of the kingdom of heaven, and who accordingly was the first to open the door of it to the Gentile world. He was the principal figure in the history of the early Christian Church, but was soon eclipsed by the overpowering presence and zeal of Paul. Tradition, indeed, has something to tell of him, but from it little of trustworthy can be gathered except that he finished his career by martyrdom in the city of Rome. This Apostle is represented in Christian art as an old man, bald-headed, with a flowing beard, dressed in a white mantle, and holding a scroll in his hand, his attributes being the keys, and a sword in symbol of his martyrdom.

[Peter, the First Epistle of], addressed especially to Jewish Christians in certain churches of Asia Minor, the members of which were suffering persecution at the hands of their adversaries as evil-doers; was written to exhort them to rebut the charge by a life of simple well-doing, and to comfort them under it with the promise of the return of the Lord.

[Peter, the Second Epistle Of], addressed to all who anywhere bore the Christian name; appears to have been written not long before his death to counteract certain fatal forms of error, at once doctrinal and practical, that had already begun to creep into the Church, and against which we meet with the same warnings in the Epistle of Jude, the doctrinal error being the denial of Christ as Lord, and the practical the denial of Him as the way, the truth, and the life, to the peril of the forfeiture of eternal life.

[Peter, the Wild Boy], a savage creature of 13 years of age, found in 1725 in a forest of Hanover, who was accustomed to walk on all fours, and climb trees like a squirrel, living on wild plants, grass, and moss, and who could not be weaned from these habits, or taught to speak more than a syllable or two; he wore a brass collar with his name on it; at length refused all food, and died in 1786.

[Peter Martyr], 1, a Dominican notorious for his severity as a member of the Inquisition, murdered by a mob at Como in 1252, became the patron saint of the Inquisition. 2, A Protestant reformer, born at Florence, became a monk and abbot at Lucca, from which, on embracing the doctrines of the Reformation, he was forced to flee, first to Switzerland and then to England in the reign of Edward VI., but had to retreat from thence also on the accession of Mary to Strasburg, and at length to Zurich, where he died (1500-1562). 3, A historian, born at Arona, rose to become bishop of Jamaica, wrote on the discovery of America, d. 1525.

[Peter the Great], emperor of Russia, son of the Czar Alexei, born at Moscow; succeeded his half-brother Feodor in 1682, but was forced for a time to share the throne with his half-sister Sophia, acting as regent for her brother Ivan; conscious of his imperfect education, he chose a Genoese named Lefort as his preceptor, and after some years' careful training he deposed Sophia, and entered Moscow as sole ruler in 1689; with the help of Lefort and Patrick Gordon, a Scotsman, he proceeded to raise and discipline an army on the European model, and determined also to construct a navy; to reach the sea he made war on the Turks, and possessed himself of the port of Azov, at the mouth of the Don; hither he invited skilled artificers from Austria, Venice, Prussia, and Holland, and a navy was built; from 1697 to 1698 he visited the countries on the Baltic and England, acquiring vast stores of information, working as a shipwright in the Dutch yards, and finally taking back with him an army of mechanics; on his return he vigorously reformed the Russian press, schools, and church, introduced European manners and literature, and encouraged foreign trade; desirous now of an opening on the Baltic, he began in 1700 a long contest with Sweden, marked first by many defeats, notably that of Narva, then the seizure of Ingria, and founding of the new capital St. Petersburg 1703, the victory of Pultowa 1712, seizure of the Baltic provinces and part of Finland 1713, and finally by the Peace of 1721, which ceded the conquered territories to Russia; in 1711 the Turks had recovered Azov; in 1722 war with Persia secured him three Caspian provinces; Peter pursued a vigorous and enlightened policy for the good of Russia, but his disposition was often cruel; his son Alexei was put to death for opposing his reforms, and on his own death he was succeeded by the Empress Catherine I., the daughter of a peasant, who had been his mistress, and whom he had married in 1712 (1672-1725).

[Peter the Hermit], a monk, born in Amiens, of good family, who is credited with having by his preaching kindled the enthusiasm in Europe which led to the first Crusade; he joined it himself as the leader of an untrained rabble, but made a poor figure at the siege of Antioch, where he was with difficulty prevented from deserting the camp; he afterwards founded a monastery near Liège, where he died (1050-1115).

[Peterborough] (25), an English cathedral city, on the Nen, partly in Huntingdonshire and partly in Northamptonshire, on the edge of the Fen country, 76 m. N. of London; has an old town-hall, manufactures of farm implements, trade in malt and coal, and is a great railway centre; the cathedral is one of the finest in Britain, of very varied architecture, was restored and reopened afterwards in 1890.

[Peterborough, Charles Mordaunt, Earl of], saw some active service as a volunteer in Charles II.'s navy, and on the accession of James II. threw himself into politics as an opponent of the king; William III. showed him great favour; he was of the Queen's Council of Regency when William was in Ireland, but imprudent intriguing brought him a short confinement in the Tower in 1697; the war of the Spanish Succession was the opportunity which brought him fame; appointed to the command of the British and Dutch forces, which fought for Charles of Austria, he reduced Barcelona 1705, and Valencia 1706; retook Barcelona from the French, and but for Charles's hindrance would have entered Madrid; differences with other generals led to his recall in 1707; the rest of his life was spent in retirement; he was the friend of Pope, and held by him in genuine esteem; he died in Lisbon (1658-1735).
