which will be more effcaual if taken from the veinb of the- 

 nrtk, or from a vein on the outfide of the eye, moiUy well 

 known to (hephords. It may even be taken from the tr>il, or 

 fore-leg ; but opening of the veins of the head !S gener- 

 ally conlidered as the moft proper and beneficial in this 

 fpecies of the complaint. As there is too great a deter- 

 mination of blood to the head, it will be attended with ad- 

 Tintage to make a determination to the bowels, by ftimu- 

 latiug them by means of purgatives, fuch as thofe of coni- 

 montalts, one ounce or more ; calomel, from ten grains to half 

 a drachm ; or, what is fuppofcd more proper, as it alfo ads 

 upon the kidney* and Ikin, a dofe of half an ounce or more 

 of nitre. Thele remedies are to be perfevered in, until all 

 marks of the difeafe difappear. But if the flieep be too far 



func in the diforder, and has loft all motion, it (hould be 

 iUed for the fake of the carcafe, which in this fpecies of 

 the difeafe is not affeaed, or at leaft but very flightly. 



In the managing of the cure, much nice attention is ne- 

 ceffary in both kinds of this difeafe.

THYATIRA, Akhlsak, a town of Afia Minor, in 

 Lydia. According to Steph. Byz. it was very ancient, 

 and called Pelope, Pelopea, or Pelopia, and afterwards Semi- 

 ramis. According to Pliny it was alfo denominated Evippa. 

 n derived its name of Thyatira, from the Greek word fignify- 

 ing daughter, from Seleucus Nicanor, who received the news, 

 33 it is faid, at this town of the birth of a daughter. From 

 an infcription found in this city, it appears that Adrian had 

 a temple in it ; and medals have been found here that were 

 ftruck in honour of Adrian. Strabo fays that the town of 

 Thyatira was confidercd by fome authors as the laft of the 

 diftrift of Mylia, and that it was a colony of Macedonians. 

 After Scipio had defeated Antiochus near Magnefia of 

 Sipyla, the town of Thyatira fent ambafladors to the Ro- 

 mans, to render them homage. Thyatira was taken by 

 Ariftonicus, in the year 130 B.C.; but this prince having 

 been taken prifoner in the fame year by the conful Perpenna, 

 this town reverted to the dominion of the Romans. Thya- 

 tira was much diftinguilhed by the benefadions of the empe- 

 ror Caracalla ; and it appears by a medal of this town, that 

 under the reign of this prince it took the name of Neocorus. 

 This place was one of the feven churches of Afia, mentioned 

 m the book of Revelations ; fo that the Chriftian religion was 

 introduced here by the apoftles and their immediate difci- 

 ples ; but whether the church was founded by St. Paul or 

 St. John, or by either of them, does not appear. 



The inhabitants of Thyatira had a particular veneration 

 for Diana. This appears from many infcriptions found in 

 the town, on one of which this goddefs bears the title of 

 " Diana Montana." The town was fituated at the fouthem 

 foot of a chain of mountains, on the route from Pergamus 

 to Sardis, and it was watered by a ilream of the river Caicus. 

 The town fufFercd much by an earthquake in the reign of 

 Tiberius. See Akhisar.

THYITES L.APis, in the Materia Medico of the An- 

 iiicnts, the name of an indurated clay, approaching to the 



THY 



nature of a ilone. It was f<iund in Egypt, and ufed in dif- 

 tempcratures of the eyes. 



Tliis fubftance has been very much mifunderftood by 

 late writers, and by moft of them fuppofed to be loft at this 

 time ; but this was wholly owing to their miftaking the clafs 

 of bodies among which they were to look for it : fome ima- 

 gining it to have been a fpecies of green marble ; and others 

 the turquoife-ftone, that Diofcorides meant by this name. 

 It is very plain, however, that it was no other than an indu- 

 r.ited clay of the morochthus kind, and no more a ftone than 

 that fubftance, that being alfo frequently called lapis mo- 

 rochthus. 



It is of a fmooth, even, and regular textui-e, very heavy, 

 of a fhining furface, and of a pale green, without the ad- 

 mixture of any other colour. It does not at all adhere to 

 the tongue, nor ftain the fingers in handling ; but drawn 

 along a rough furface, leaves a flender white hne. It melts 

 flowly in the mouth, and is of a fharp, acrid, and difagree- 

 able tafte ; and when rubbed down with water on a marble, 

 it melts into a milky liquor of a pure white, not the leaft 

 greennefs being fenfible in it. It is found at prefent in the 

 great mine at Gofielar in Saxony, and feems to owe its co- 

 lour to particles of copper, to which alfo it owes the virtues 

 attributed to it by Diofcorides, afting as a weak kind of 

 verdigris. Hill.

 Dai-danus, who gave it its name after that of his friend 

 Thymbros. Apollo had a temple here under the appellation 

 of Thymbrian. Strabo fays that a ftream called Tym- 

 brius traverfed its canton, and that this ftream difcharged 

 itfelf into the Scamander, before the temple of Apollo. 

 Servius fays that Achilles was wounded here by Paris ; and 

 this circumftance gave occafion to the report that the wound 

 was infliiled by Apollo.
