HIPPEASTRUM, in botany, a genus of the natural order Amaryllidaceae, containing about 50 species of bulbous plants, natives of tropical and sub-tropical South America. In cultivation they are generally known as Amaryllis. The handsome funnel-shaped flowers are borne in a cluster of two to many, at the end of a short hollow scape. The species and the numerous hybrids which have been obtained artificially, show a great variety in size and colour of the flower, including the richest deep crimson and blood-red, white, or with striped, mottled or blended colours. They are of easy culture, and free-blooming habit. Like other bulbs they are increased by offsets, which should be carefully removed when the plants are at rest, and should be allowed to attain a fair size before removal. These young bulbs should be potted singly in February or March, in mellow loamy soil with a moderate quantity of sand, about two-thirds of the bulb being kept above the level of the soil, which should be made quite solid. They should be removed to a temperature of 60° by night and 70° by day, very carefully watered until the roots have begun to grow freely, after which the soil should be kept moderately moist. As they advance the temperature should be raised to 70° at night, and to 80° or higher with sun heat by day. They do not need shading, but should have plenty of air, and be syringed daily in the afternoon. When growing they require a good supply of water. After the decay of the flowers they should be returned to a brisk moist temperature of from 70° to 80° by day during summer to perfect their leaves, and then be ripened off in autumn. Through the winter they should have less water, but must not be kept entirely dry. The minimum temperature should now be about 55°, to be increased 10° or 15° in spring. As the bulbs get large they will occasionally need shifting into larger pots. Propagation is also readily effected by seeds for raising new varieties. Seeds are sown when ripe in well drained pans of sandy loam at a temperature of about 65°. The seedlings when large enough to handle are placed either singly in very small pots or several in a pot or shallow pan, and put in a bottom heat, in a moist atmosphere with a temperature from 60° to 70°. H. Ackermanni, with large, handsome, crimson flowers—itself a hybrid—is the parent of many of the large-flowered forms; H. equestre (Barbados lily), with yellowish-green flowers tipped with scarlet, has also given rise to several handsome forms; H. aulicum (flowers crimson and green), H. pardinum (flowers creamy-white spotted with crimson), and H. vittatum (flowers white with red stripes, a beautiful species and the parent of many varieties), are stove or warm greenhouse plants. These kinds, however, are now only regarded as botanical curiosities, and are rarely grown in private or commercial establishments. They have been ousted by the more gorgeous looking hybrids, which have been evolved during the past 100 years. H. Johnsoni is named after a Lancashire watchmaker who raised it in 1799 by crossing H. Reginae with H. vittatum. Since that time other species have been used for hybridizing, notably H. reticulatum, H. aulicum, H. solandriflorum, and sometimes H. equestre and H. psittacinum. The finest forms since 1880 have been evolved from H. Leopoldi and H. pardinum.

HIPPED ROOF, the name given in architecture to a roof which slopes down on all four sides instead of terminating on two sides against a vertical gable. Sometimes a compromise is made between the two, half the roof being hipped and half resting on the vertical wall; this gives much more room inside the roof, and externally a most picturesque effect, which is one of the great attractions of domestic architecture in the south of England, and is rarely found in other countries.
HIPPEL, THEODOR GOTTLIEB VON (1741-1796), German satirical and humorous writer, was born on the 31st of January 1741, at Gerdauen in East Prussia, where his father was rector of a school. He enjoyed an excellent education at home, and in his sixteenth year he entered Königsberg university as a student of theology. Interrupting his studies, he went, on the invitation of a friend, to St Petersburg, where he was introduced at the brilliant court of the empress Catherine II. Returning to Königsberg he became a tutor in a private family; but, falling in love with a young lady of high position, his ambition was aroused, and giving up his tutorship he devoted himself with enthusiasm to legal studies. He was successful in his profession, and in 1780 was appointed chief burgomaster in Königsberg, and in 1786 privy councillor of war and president of the town. As he rose in the world, however, his inclination for matrimony vanished, and the lady who had stimulated his ambition was forgotten. He died at Königsberg on the 23rd of April 1796, leaving a considerable fortune. Hippel had extraordinary talents, rich in wit and fancy; but his was a character full of contrasts and contradictions. Cautiousness and ardent passion, dry pedantry and piety, morality and sensuality; simplicity and ostentation composed his nature; and, hence, his literary productions never attained artistic finish. In his Lebensläufe nach aufsteigender Linie (1778-1781) he intended to describe the lives of his father and grandfather, but he eventually confined himself to his own. It is an autobiography, in which persons well known to him are introduced, together with a mass of heterogeneous reflections on life and philosophy. Kreuz- und Querzüge des Ritters A bis Z (1793-1794) is a satire levelled against the follies of the age—ancestral pride and the thirst for orders, decoration and the like. Among others of his better known works are Über die Ehe (1774) and Über die bürgerliche Verbesserung der Weiber (1792). Hippel has been called the fore-runner of Jean Paul Richter, and has some resemblance to this author, in his constant digressions and in the interweaving of scientific matter in his narrative. Like Richter he was strongly influenced by Laurence Sterne.
In 1827-1838 a collected edition of Hippel’s works in 14 vols., was issued at Berlin. Über die Ehe has been edited by E. Brenning (Leipzig, 1872), and the Lebensläufe nach aufsteigender Linie has in a modernized edition by A. von Öttingen (1878), gone through several editions. See J. Czerny, Sterne, Hippel und Jean Paul (Berlin, 1904).
HIPPIAS OF ELIS, Greek sophist, was born about the middle of the 5th century B.C. and was thus a younger contemporary of Protagoras and Socrates. He was a man of great versatility and won the respect of his fellow-citizens to such an extent that he was sent to various towns on important embassies. At Athens he made the acquaintance of Socrates and other leading thinkers. With an assurance characteristic of the later sophists, he claimed to be regarded as an authority on all subjects, and lectured, at all events with financial success, on poetry, grammar, history, politics, archaeology, mathematics and astronomy. He boasted that he was more popular than Protagoras, and was prepared at any moment to deliver an extempore address on any subject to the assembly at Olympia. Of his ability there is no question, but it is equally certain that he was superficial. His aim was not to give knowledge, but to provide his pupils with the weapons of argument, to make them fertile in discussion on all subjects alike. It is said that he boasted of wearing nothing which he had not made with his own hands. Plato’s two dialogues, the Hippias major and minor, contain an exposé of his methods, exaggerated no doubt for purposes of argument but written with full knowledge of the man and the class which he represented. Ast denies their authenticity, but they must have been written by a contemporary writer (as they are mentioned in the literature of the 4th century), and undoubtedly represent the attitude of serious thinkers to the growing influence of the professional Sophists. There is, however, no question that Hippias did a real service to Greek literature by insisting on the meaning of words, the value of rhythm and literary style. He is credited with an excellent work on Homer, collections of Greek and foreign literature, and archaeological treatises, but nothing remains except the barest notes. He forms the connecting link between the first great sophists, Protagoras and Prodicus, and the innumerable eristics who brought their name into disrepute.
