440 PLINY'S NATUKAL HISTORY. [Book XXXVff? - 



according to their respective colours, I shall proceed to mention 

 the rest of them in their alphabetical order. 



(10.) Achates 18 was a stone formerly in high esteem, lut 

 now held in none. It was first found in Sicily, near a river 

 of that name ; but has since been discovered in numerous other 

 localities. In size it exceeds any other stones of this class, 

 and the varieties of it arc numerous, the name varying accord- 

 ingly. Thus, for example, we haveiuspuchutes, 15 eerachates, 20 

 smiiragdachates, 21 hsemachates, 22 leueaehates, 83 dendruchates, 24 

 marked with small shrubs, as it were; autachates, 24 which when 

 burnt has a smell like that of myrrh ; and coralbachates, 20 

 spotted all over, like sapphiros, with drops of gold, and com- 

 monly found in Crete, where it is also known as " sacred" 

 achutes. This last, it is thought, is good for wounds inflicted 

 by spiders and scorpions ; a property which I could really 

 believe, to belong to the stones of Sicily, for, the moment they 

 breathe the air of that province, scorpions lose their venom. 



The stones, too, that are found in India are possessed of 

 similar properties, and of other great and marvellous properties 

 as well ; for they present the appearance in them of rivers, 27 

 woods, 21 * beasts of burden, and forms even, like ivy 29 and the 

 trappings of horses. Medical men, too, make grind ing- hones 30 

 of these stones, and indeed the very sight of them is beneficial 

 for the eyes: held in the mouth, they allay thirst. Those 

 found in Phrygia have no green in them, and those of Thebes 

 in Egypt are destitute of red and white veins. These last arc 

 good us a counterpoison to the venom Of the scorpion, and the 

 stones of Cyprus are held in similar repute. Some persons sot 

 the highest value upon those stonus which present a trans- 

 parency like that of glass. They are found also in Trachinia,
