TRICOMIA, a town of Afia, in Phrygia Major. 

 TRICOR, a name by which fonie of the chemical 

 writers have called gold. 



TRICORD, an ancient mufical inftniment with three 

 ftrintrs. The firfl; lyre of Mercury is fuppofed by many to 

 have had but three ftrings. Moft of the writers on mufic 

 araong the ancients, have fuppofed that the three founds of 

 this primitive lyre, were E, F, G. 



Julius Pollux called the pandora, or pandura, the inftru- 

 Rient with three ftrings. 



The emperor Heliogabalus, fays Lampridius, fung, 

 danced, recited, or declaimed to the found of the flute, 

 founded the tnimpet, played on the pandura and the 

 organ. 



Here is work for ingenious conjeftures : what was meant 

 by reciting to the flute ? What mufic could an inftrument 

 without a neck produce with only three ftrings ? And what 

 Jcind of inftrument was the organ upon which Heliogabalus 

 played, before organs were fuppofed to have been invented ? 

 TRICORII, in Ancient Geography, a people of Gallia 

 Narbonnenfis, mentioned by Lucan in his Pharfaha, and alfo 

 by Livy and Polybius, in their account of the march of 

 Hannibal. Livy fays that Hannibal, having parted the 

 Rhone, took his route on the left, through the countrj' of 

 the Tricaftini, and touching on the ten-itory of the Vocon- 

 tii, entered into that of the Tricorii. Afcending along the 

 Rhone, he arrived on the fourth day of his march at the 

 junftion of a river with the Rhone, on the confines of the 

 AUobroges, who inhabited the territory between thefe 

 rivers. This river is called Scoras by Polybius, and Arar 

 (the Saone) by Livy. Some critics, however, are of opinion 

 that this name is erroneous, and that it was Ifere.

TRICRATUS, in Botany, fo named by the late M. 

 I'Heritier, from tjeic, three, and /.fazo^,, poiuer, or di/linc- 

 t'lon ; perhaps in allufion to the three-fold affinity or refem- 

 blance of the plant, indicated by Juflieu, who remarks that 

 it has the habit of Valeriana, the flowers of Primula, and 

 nearly the charafter of Mirabilis. We ftill do not perceive i 

 any reafon for Juflieu's original name, Abronia, (from a/Sfo;, "
