Perpendicular Style

the third period of Pointed Architecture. It originated at the end of the 11th century, and continued till the close of the 16th, when it was succeeded by the Revived, or Debased Classic, known as the Elizabethan. It is also known as the Florid, from the multiplicity, profusion, and minuteness of ornamental detail, and its more general name, Perpendicular, is derived from the mullions of the windows and the divisions of ornamental panel work running in straight or pependicular lines, which was not the case in any earlier style. The pointed arches are constructed from almost every radius. The most common doorway is the depressed four-centered arch (almost peculiar to this style) within a square head, having generally a hood molding over, the spandrels being filled with quatrefoils, paneling, roses, foliage, small shields, or other sculptured ornaments. Fan-shaped roofs, ornamented with dependent pendants resembling stalactites, are also peculiar to the Perpendicular style. Richly decorated roof trusses, which are left clearly visible, are also of frequent occurrence. In these roofs the spaces between the highly ornamented and molded beam are filled with rich tracery.

Perpetual Motion

a motion which, once generated by mechanical means, should have the power of perpetuating itself. A machine which, according to the hopes of its inventors, after it has once set in motion, will keep in motion without drawing on any external source of energy. As early as 1775 the Académie des Sciences of Paris placed the problem in the same category with the duplication of the cube and the quadrature of the circle, and refused to receive schemes claiming to have overcome the difficulty-in reality, to have performed the impossible. The overbalancing wheel was a favorite contrivance with the seekers after a perpetual motion. It appears as early as the 13th century.

Perpignan

a town of France, and a fortress of the first rank; in the department of Pyrénées-Orientales, on the river Têt, 7 miles from the Mediterranean, 40 S. of Narbonne, and 17 from the Spanish frontier. It commands the passes of the Eastern Pyrénées, and is defended on the S. by a citadel, which incloses the old castle of the Counts of Roussillon, and by a detached fort. The streets are narrow and the houses of semi- Moorish construction, and show evidences of Spanish influence. The cathedral (begun in 1324), the Moorish-Gothic cloth hall or bourse (1396), the town house (1692), the building of the former university (1349-French Revolution), the court house, and a col college are the principal public buildings. Good red wine is made, sheep and silkworms are bred, vegetables and fruit grown, brandy distilled, cloth woven, and corks cut; and there is a good trade in wine, spirits, wool, cork bark, oil, cloth, and silk. As capital of the former county of Roussillon Perpignan was in the hands of the kings of Aragon from 1172 to its capture by France in 1475; it was restored to Spain in 1493; but Richelieu retook it in 1642, and France has possessed it ever since. Pop. (1911) 39,510.

Perrault, Charles

pa-ro, Charles (1628-1703), a French poet and story writer. Perrault was a man of wide learning. His name was brought into prominence by a famous literary controversy between himself and Boileau, as to the respective merits of the ancients and moderns. Perrault's poetry was not of a high order and won him no lasting fame. He is better known as the author of two prose works, Illustrious Men of the Seventeenth Century and a collection of stories entitled Tales of Mother Goose . These were from varied sources, some of oriental origin but retold in modern form. The book is mentioned frequently as Perrault's Tales. It includes eighteen stories. Among them are Puss-in-Boots, Cinderella, Bluebeard, and Little Red Riding-Hood.

Perry, Oliver Hazard

Oliver Hazard (1785-1819), an American sailor. He was born at South Kingston, Rhode Island , and died at Port Spain, Trinidad. He was trained as a midshipman in the United States navy, and served in the Tripolitan War. In the War of 1812 he defeated the British in the celebrated battle of Lake Erie, September 10, 1813. He announced his victory to General Harrison in the oft quoted words, "We have met the enemy and they are ours." This victory enabled Harrison to invade Canada. Perry pursued Proctor's squadron up the Thames and won a second victory October 5, 1813, at Put-in-Bay, near Detroit. These victories were of great service in recovering possession of Michigan. At the close of the war Perry received a vote of thanks from Congress, a medal and the rank of captain. In 1905 three of Proctor's ships were found in the Thames. The red oak and walnut used in the construction of the hulls was found as sound as the day it was hewn from the forest. About two tons of cannon balls were found, but no cannon. It is supposed that the cannon were thrown overboard. One of the ships lay buried in a sand bank beneath eighteen feet of soil, 100 yards from the present center of the stream. A tree three feet in diameter was found growing above it.
