An´tiphon, a Greek orator, born near Athens; founder of political oratory in Greece. His orations are the oldest extant, and he is said to have been the first who wrote speeches for hire. He was put to death for taking part in the revolution of 411 B.C., which established the oligarchic government of the Four Hundred. Antiphon seems to have specialized in homicide cases; his most celebrated speech is On the Murder of Herodas. Cf. Sir R. C. Jebb, Attic Orators; J. F. Dobson, The Greek Orators.

Antiphon, or Antiph´ony ('alternate song'), in the Christian Church a verse first sung by a single voice, and then repeated by the whole choir; or any piece to be sung by alternate voices.

Antipodes (an-tip´o-dēz), the name given relatively to people or places on opposite sides of the earth, so situated that a line drawn from one to the other passes through the centre of the earth and forms a true diameter. The longitudes of two such places differ by 180°. The difference in their time is about twelve hours, and their seasons are reversed.

Antipodes Islands, a group of small uninhabited islands in the South Pacific Ocean, about 460 miles S.E. by E. of New Zealand; so called from being nearly antipodal to Greenwich.

An´tipope, the name applied to those who at different periods have produced a schism in the Roman Catholic Church by opposing the authority of the Pope, under the pretence that they were themselves Popes. The Roman Church cannot admit that there ever existed two Popes; but the fact is, that in several cases the competitors for the papal chair were equally Popes; that is to say, the claims of all were equally good. Each was frequently supported by whole nations, and the schism was nothing but the struggle of political interests. Twenty-nine antipopes are enumerated in Church history; the last of them is Felix V, 1439-49.

Antipyret´ics, medicines given for the purpose of reducing fever by lowering the patient's temperature, whether by causing perspiration or otherwise. Quinine, antipyrin, phenacetin, are common antipyretics. An aperient or purgative often serves the same purpose.

Antipy´rin, a drug obtained from coal-tar products, valuable in reducing fever and in relieving pain, being much used in nervous headache and neuralgia.

An´tiquaries, those devoted to the study of ancient times through their relics, as old places of burial, remains of ancient habitations, early monuments, implements or weapons, statues, coins, medals, paintings, inscriptions, books, and manuscripts, with the view of arriving at a knowledge of the relations, modes of living, habits, and general condition of the people who created or employed them. Societies or associations of antiquaries have been formed in all countries of European civilization. In Britain the Society of Antiquaries of London was founded in 1572, revived in 1717. and incorporated in 1751. The Society of Antiquaries of Scotland was founded in 1780, incorporated in 1783, and has the management of a large national antiquarian museum in Edinburgh. One of the best-known antiquarian societies in Europe is the Société Royale des Antiquaires du Nord at Copenhagen.
