XV f. Observations on Two Ancient Etruscan Coins. By the Rev. John Swin- 



ton, B. D., F. R. S. p. 99. 



These two small Etruscan coins or weights, are each of them an uncia, or 

 12th part of an as, and in pretty good conservation. The weight or value of 

 each piece appears from a single globule on the reverse. The first of these 

 medals presents a diademated head, somewhat deformed by the injuries of time. 

 The workmanship is rude, such as we find it to be in many of the more ancient 

 Etruscan coins. The slip of metal projecting from the round of the weight 

 demonstrates the piece to have been cast, and may therefore be considered as a 

 certain indication of its high antiquity. From the globule and two letters, t v, 

 on the reverse, we may infer this coin to have been a stips uncialis of the Tu- 

 dertes, or people of Tuder, TOTAEP, as this ancient city of Italy seems to have 

 been called by Strabo. This small Etruscan uncia weighs precisely 3 dwts. 1 gr. 



The second piece exhibits on one side the head of Hercules, adorned with a 

 lion's skin ; behind which a fish resembling the turso, or tyrso, appears, witK 

 3 Etruscan letters well enough preserved. On the reverse are a dolphin, or 

 tyrso, part of an anchor, and another fish under the former. A single globule, 

 or uncial mark, determining the weight or value of the piece, is also visible here. 

 The workmanship is somewhat rude, and different from that of the Romans. 

 The tyrso seems to allude to the origin and most ancient name of the Etruscans, 

 who were called Tyrsenians by the Greek writers that flourished before Polybius. 

 The forms of the letters on this medal are exactly the same with those of the 

 correspondent elements used in Umbria and the Proper Etruria, and apparently 

 answer to the Roman letters fai, probably referring to the town of Faesul« m 

 the Proper Etruria.
