TRISAGION, or Tkisagium, T^Kj-seyw^, compounded 

 of Tjsjf, three, and aymc, JanCfus, holy, in Church Hi/lory, a 

 hymn, in which the word holy is repeated three times. 



The proper Trifagion is thofe words. Holy, holy, holy. 

 Lord God of Saliaoth, which we read in Ifaiah, vi. 3. and 

 in the Apocalypfe. From thefe words the church formed 

 another trifapjion, which is rehearfed in Latin and Greek, 

 in the refpeflive churches, to this effeA, Holy God, Holy 

 Mighty, Holy Immortal! have mercy upon us. Petrus Ful- 

 lenfis to this trifagion added, rayfw9«5 ll >)V»5> Thou who 

 •wajl cruc'ified for us — have mercy, &c. thus attributing the 

 paflion, not to the Son alone, but to all the three perfons of 

 the Trinity ; and he pronounced anathema to all fuch as 

 would not fay the fame. See Theopaschite. 



The ufe of the fecond trifagion (exclufive of the addi- 

 tion of FuUenfis) began in the church of Conllantinople, 

 from whence it pafled into the other churches of the Eaft, 

 and afterwards into thofe of the Weft : and ftill fubfills 

 in its primitive purity, both in Latin, Greek, Ethiopic, and 

 Mozarabic offices. 



TRISAKTI, or Trisakti-devi, in Hindoo Mythology, 

 is a name of the goddofs Parvati, confort of Siva. It 

 means of triple energy ; both god and goddefs having 

 various triform characters and potencies, and many names 

 indicative of three-fold properties. Parvati is found to 

 have many attributes and appellations correfponding with 

 thofe of the Grecian Juno or Diana : among them feveral 

 derived from their three -fold charafter. Trivia, for in- 

 ftance ; and by the way, the meeting or junftion of roads 

 was myftei-iou/ly facred to both. See JtJNCTiON. 



Tritonea, Tergemania, &c. are appellations of the Triple 

 Hecate. See Potter's Archoeol. Grsec. ch. xix. 



TRISANTHLiS, in Batavy, from i^^:, three, and avSo,-,

I. T. cochinchinenjis. Rau ma of the Cochinchinefe. 

 The only defcribed fpecies, frequent about hedges in 

 Cochinchina, where, though an efculent herb, it is not cul- 

 tivated. The author thought he had alfo met with this 

 plant in China, as well as other parts of the Eaft Indies ; 

 and he cites the Pes equinus of Rumphius, book 9. chap. 69. 

 t. 169. f. I, which is no other than Hydrocotyle ajiatica oi 

 Linnsus. They may be one and the fame, as Loureiro 

 was mofl: inclined to beheve. He defcribes his Trifanthus 

 with a long, trailing, flender, thrcad-(haped_^fff(, taking root 

 at nearly regular intervals. Leaves from the fame points as 

 the roots, roundlfli, concave, rugofe, fmooth, crenatc, divided 

 half v/ay down, on long, ereti footjlalks. Germen purple, 

 which Loureiro takes for a perianth inverting the feed, 

 and becoming a pericarp. The Jlower-Jlalks are radical, 

 crowded, rather long. 



The whole plant is faid to be vulnerary, cleanfing, 

 diuretic, and nephritic. Loureiro knew a man who, having 

 deprived himfelf, at a Itroke, of parts which moil people 

 wifli to preferve, healed the wound readily by the applica-

tion of this herb, mixed with a fuialt quantity of powdered 

 lime. A notable cure no doubt ! but which few perfons 

 will be anxious to verify by experiment, and which Hill 

 fewer, probably, would try with perfeft fatisfaftioii or 

 fuccefs. 



TRISC^DECACTIS, in Natural Hiftory, a name 

 given by Linkius, and fame other authors, to a kind of 

 branched ftar-fi(h, or aftrophyte, whofe rays are thirteen 

 in number, where they iirft leave the body, and each divides 

 into many more. 



TRIS-DIAPASON,TRiPi.E-DiAPASON,inM«/?<:,what 



is otherwife called a triple eighth. 



TRISE, at Sea, the feamen's word for hahng up of any 

 thing with a dead-rope, or one that doth not run in a block, 

 but is pulled by hand or by main ftrength : thus if any ca/k, 

 cheft, or other goods, hath only a rope faftened to it, and 

 fo without a tackle be pulled up into a fliip by hand, they 

 fay it is trifed up. 



TRISECTION, or Trissection, the dividing of a 

 thing into three. 



The term is chiefly ufed in Geometry, for the divifion of 

 an angle into three equal parts. 



The trifedion of an angle geometrically, is one of thofe 

 great problems whofe folution has been fo much fought by 

 mathematicians for two thoufand years ; being, in this rc- 

 fpeft, on a footing with the quadrature of the circle, and 

 the duphcature of tlie cube angle. 



Several late authors have written of the tcifeftion of the 

 angle, and pretend to have found out the demonftration 

 of it ; but they have all committed paralogifms. 



TRISETiE, the three-lmired jiies, a term ufed by the 

 writers in Natural Hijlory, to expiefs a certain genus of the 

 feticauds, or briftle-tailed flies, which are diftinguifhed 

 from the reil, by having thres huirs or briftlcs growing 

 from the tail ; there are feveral kinds of thefe flies, found 

 frequently among our hedges. 



TRISETUM, 1h Botany, apparently fo called becaufe the 

 corolla was fuppofcd to have three awns, is a genus of graffes, 

 adopted by Purfii, Fl. Amer. Sept. 26 and 76, for which he 

 cites 'Perioan's. Enchiridion, v. i. 97, and gives the following 

 eflential charafter. 



Calyx two or three-flowered, pointed, keeled. Corolla 

 with two terminal awns, and a folltary dorfal one, vvliich is 

 ilraight, not twilled. Florets fmooth. 



The only fpecies mentioned by Mr. Purfli, is called T. 

 pratenfc, and is fald to be Avenajtavrfccns of former autliors. 

 If it be the European plant, fo well known under that n:in;e, 

 we can mofl indubitably aver that it does not anfwer to tlie 

 above charafter, the corolla having tv\o t:;per points, liice 

 many other graffes ; but nothing lixe awns except the large 

 fohtary dorfal one, which is as certainly twilled as tiiat of 

 all other A-Dcna. 



TRISEUS, in Ichthyology, a name given by Salvian, 

 Benediftus Jovius, and other.,, to that fpecies of the gadi 

 which we call the eelpout, and authors in general the mujlela 

 Jluviatil':s. See GauUS Lota. 



TRISIRAS, in Hindoo Mythology, is the name of a dog 

 appertaining to their god Yama, the regent of heU. 



This reminds us at once of the Cerberus of the Grecian 

 Pluto, the more particularly as the Hindoo dog is repre- 

 fented to be three-headed, wliich indeed is the literal tranlla- 

 tion of Trifiras. 



TRISMEGISTUS, formed from r^a;, thrice, and

 two Hermcfes, or Mercuries, kings of Thebes, m Eg>-pt, 

 who was contemporary with Mofes.
