There have been feveral Trifacramentarians among the Proteftants, who allow'd of Baptifm, the Eucharift, and Abfolution, for Sacraments. — The Englifi are often mifre- prefented by Foreigners as Trifacramentari&ns, from an Opi- nion that they allow Ordination a Sacrament. See Ordi- nation.

TRISAGION, or Trisagium, in Church Hiftory, a Hymn, wherein the Word holy is repeated three Times, See Hymn.

The proper Trifagion is thofe Words holy, holy, holy, Lord God of Hofs, which we read in Ifaiah »/i. 3 . and in the Apo- calypfe.

From thefe Words, the Church form'd another Trifagion, which is rehears'd in Latin and Greek, in the refpcclive Churches, to this Effect : Holy God, holy Forty holy Im- mortal l have Mercy upon us.

Tetrus Fullenfis to this Trifagion added, Thou who waft cruciffd for us, have Mercy upon us : Thus attributing the Paflion not to the Son alone, but to all the three Perfbns of the trinity, and pronouncing Anathema to all fuch as would not fay the fame.

The Ufe of this latter 'Trifagion, (exclufive of the Additi- on of Fullenfis) began in the Church of Confiantinople, from whence it pafsM into the other Churches of the Eaft, and afterwards into thofe of the Weft. — tDamajcentls, Codin, Salfamon, and others, fay it was in the Time of the Patri- arch 'Prochts that it was firft introdue'd, and on the follow- ing Occafion : There being a violent Earthquake in the 35th Tear of the younger T 'heoiofus, the Patriarch made a grand Proceffionj wherein, for feveral Hours together, was' fung the Kyrie Eleifon, Lord have Mercy upon us. While this was in Hand, a Child was taken up into the Air, where, it feems, he heard the Angels a fihging the Trifagion juft men- tionM. He return'd fbon after, and told what he had heard : Upon which ihey began to jSng that Hymn, and the more willingly too, as they attributed the Troubles they were then under to the Blafphemies which the Hereticks of Confian- tinople utter'd againft the Son. — Afclepiades, Cedremts, Pope Felix, Nicephor*is, Sec. relate the fame Story.

^Petrus Fullenfis, Patriarch of Antioch, and a zealous Par- tizan of Neftorius, endeavour'd to corrupt the Hymn, by add- ing, who fi/jfer'd for US ; but in vain : It fiill fubfifls in its primitive Purity, both in the Latin, Greek, Ethiopic, and Mofarabic Offices; See Patrip assions.

Several People out of Fear of giving into Tritheifm have become Sabellians ; and feveral others, to avoid Sabelliamfm^ have commene'd Tritheifis ; fo delicate and fubtle is the Me- dium. See Sabellian.

In the famous Controverfy between Dr. South and Dr.' Sherlock, the firit is judg'd to have run into Sabellianifm, bv a too rigorous afferting of the Unity of the Godhead ; ancl the latter into Tritherfm, by a too abfolute maintaining the Trinity.

John the Grammarian, furnam'd Philcponus, Lover of Labour, is held the Author of the Seel: of the Tritheifts, under the Emperor 'Phocas ; at leaft it appears he was a zea- lous Advocate thereof. Leonthts and Georgius ^Pijtdes wrote againfl; him

TRITON, in Poetry, a Sea Demi-God, held by the An- cients to be an Officer or Trumpeter of Neptune, attending on him, and carrying his Orders and Commands from Sea to Sea. See God.

The Poets and Painters rcprefent him as half Man, half Fifn, terminating in a Dolphin's Tail, and bearing in one Hand a Sea-fhell, which fe~v'd as a Trumpet.

Some of the Ancients make him the Son of Neptune, and the Nymph Salacia - y Hefiod of Neptune and Amphitrite ; Neurmnius in his Book de Tifcatwifois, makes him the Son of Ocean and Tethy's ; and Lycophron the Son of Neptune. . But tho' Hefiod, and the iMythoio-ifrs, only fpeak of one Triton, yet the Poets have imagin'd Several 5 giving fome of them for Trumpeters to all the Sea-Gods, particularly toNep- tune and Venus : accordingly they were frequently introdue'd on the ancient Theatres, and in the Naumachia.

In effect^ the Tnt&tt not only officiated as Trumpeters in Nepttme's Retinue, but were alfo fuppos'd to draw his Cha- riot, ii e. the Sea-fhell wherein he rode over the Waters, as we find in Virgil JEmid X. 209. Ovid Met am. I. 3 33. and on a Medal of Claudius.

The Fable of the Tritons, no doubt, took its Rife froni Sea or Mer-men ; for that there are fuch Things as Sea-men, would feem a Thing fcarce to be doubted, after what we have faid under the Article MzR-maid.

The Poets ordinarily attribute to Triton the Office of calm- ing the Waves, and of making Tempeirs ceafe. -- Thus in the ill of the Metamorphofes we read, that Neptune defiring to recal the Waters of the Deluge, commanded Triton to found his Trumpet, at the Noife whereof the Waters all retir'd.

Its Ratio, or Proportion in Numbers, is of 45 to n- In dividing the Octave, we find, on one Side, the falfe Fifth, and the Tritone on the other. Sec Octave.

The Tritone is a kind of redundant Third, confifling of three Tones, whence its Name ; or, more properly, of two Tones, with a greater Semitone, and a letter, as of tit to fa, of fa to ft, £ffc —But it is not, as many imagine, a greater Fourth ; for the Fourth is a perfeft Interval, which does not admit of any Majority or Minority: Nor muft the Tritone be confounded with the falfe Fifth ; for the Tritons only comprehends four Degrees, viz., ut, re, mi, fa, whereas the [ S f f ] fa,li*
