HYMEN 100 HYPATIA HYMEN, the Greek god of marriage, was son of Bacchus and Venus, or, ac- cording to another version, of Apollo and one of the Muses. The people of Athens instituted festivals in his honor, and solemnly invoked him at their nup- tials, as the Latins did their Thalassius. Hymen was represented as crowned with flowers, holding a burning torch in one hand, and in the other a wreath. In anatomy, the name denotes the semi- lunar, parabolic, or circular membrane situated at the outer orifice of the va- gina in virgins. PAUL HYMANS HYMENOPTERA (hi-men-op'ter-a) , an order of insects, containing about 25,000 species, and now usually acknowl- edged to stand at the head of the class of insects, and of which many, as ants and bees, are singularly interesting and important. HYMETTUS, a mountain in Attica, Greece; now called Trelo Vouni, to the S. E. of Athens; was famous among the ancients for its honey and its bluish marble. The honey is still in repute. HYMN, a sacred composition in poetry intended to be sung with or without the aid of a musical instrument, and not being versified from the book of Psalms, else it is called a Psalm, or directly from any other part of Scripture, or else it is a paraphrase. Hilary, Bishop of Aries, is said to have composed the first hymn for Christian worship about A. D. 431, but as early as the time of Pliny the Younger the Christians are said to have habitually sung one to Christ as God. On Dec. 9, 633, the Coun- cil of Toledo sanctioned the use of hymns in churches. Luther did much to popu- larize hymnody in the infant Protestant Church in Germany. Of the hymns now in use many were composed by Isaac Watts, Charles Wesley, John Wesley, Cowper, John Newton, James Montgom- ery, John Henry Newman, Frederick William Faber, and Frances Ridley Havergal. Prominent among Americans who have written hymns are Oliver Wen- dell Holmes, Phcebe Gary, P. P. Bliss, Ira D. Sankey, Julia Ward Howe, who wrote "The Battle Hymn of the Republic," Samuel Francis Smith, author of the na- tional hymn "America," Timothy Dwight, Ray Palmer, who wrote "My Faith Looks up to Thee," Joseph Henry Gilmore, etc. HYMNOLOGY (-nol'6-ji), a collection of hymns; hymns collectively; the hymns used by any particular Church or body.

HYPATIA (hi-pa'she-a) , an Alexan- drian teacher and heroine; born in Alex- andria between 370-880. She was the daughter of Theon, an eminent mathe- matician of Alexandria, whom she suc- ceeded in the government of that school.

Between the governor and the patriarch Cyril there was bitter enmity, which broke out into open war, and the monks siding with their chief.
