CHAP. 10. (7.) STONE OF NAXOS. STONE OF ARMENIA. 



For polishing marble statues, as also for cutting and giving 

 n polish to precious stones, the preference was long given to 

 the stone of .Xaxos," such being the name of a kind of toueh- 

 Ftone* that is found in the Isle of Cyprus. More recently, 

 however, the stones imported from Armenia for this purpose 

 have displaced those of JN'axos. 



CHAT 11. THE MAKULES OF ALEXANDRIA. 



The marbles arc too well known to make it necessary for 

 me to enumerate their several colours and varieties ; and, 

 indeed, PO numerous are they, that it would he no easy task to 

 do so. For what place is there, in fact, that has not a marble 

 of its own ? In addition to which, in our description of the 

 earth and its various peoples, 64 we have already made it our 

 care to mention the more celebrated kinds of marble. Still, 

 however, they are not all of them produced from quarries, but 

 in many instances lie scattered just beneath the surface of the 

 earth ; some of them the most precious even, the green Lace- 

 dsemonian marble, for example, more brilliant in colour than 

 any other; the Augustan also; and, more recently, the Tiberian; 

 which were first discovered, in the reigns respectively of 

 Augustus and Tiberius, in Egypt. These two marbles differ 

 from ophite*** in the circumstance that the latter is marked 

 with streaks which resemble serpents 50 in appearance, whence 

 its name. There is also this difference between the two 

 marbles themselves, in the arrangement of their spots : the 

 Augustan marble has them undulated and curling to a point; 

 whereas in the Tiberian the streaks are white, 57 not involved, 

 but lying wide asunder. 



Of ophites, there are only some very small pillars known to 

 have been made. There arc two varieties of it, one white 

 and soft, the other inclining to black, and hard. IJoth kinds, 

 it is said, worn as an umulet, arc -a cure for head-ache, and for
