near the city of Celaenae, in Phrygia, which throws up masses 

 of stone. Not far from it are two other springs, called Claeon 60 

 and Gelon by the Greeks, from the effects which they re- 

 spectively produce. At Cyzicus is a fountain known as that 

 of Cupido, the waters of which, Mucianus believes, 61 cure those 

 who drink thereof of love. 



CHAP. 17. WATEKS WHICH PEESERVE THEIR WARMTH FOR THREE 

 DAYS. 



At Crannon 62 there are certain hot springs, though not at 

 boiling heat, the water of which, mixed with wine, preserves 

 it warm in the vessels for a period of three days. The same is 

 the case, too, with the springs of Mattiacum 63 in Germany, 

 beyond the river Ehenus, the water of which retains its boil- 

 ing heat three days. The margin of these springs is covered 

 with pumice, formed by the action of the water. 



CHAP. 18. OTHER MARVELLOUS FACTS CONNECTED WITH WATER. 

 WATERS IN WHICH EVERYTHING WILL SINK. WATERS IN WHICH 

 NOTHING WILL SINK. 



If any of the above-mentioned facts have the appearance 

 of being incredible to a person, I would have him know that 

 there is no department of Nature which presents greater mar- 

 vels than this, independently of the numerous peculiarities 

 which have been already mentioned 64 in an earlier part of this 

 work. Ctesias informs us that, in India, there is a lake of 

 standing water, upon which nothing 65 will float, every object 

 instantly sinking to the bottom. Caelius says that in the 

 waters of Lake Avernus, 66 in our own part of the world, the 

 very leaves of the trees even will sink ; and, according to 

 Varro, these waters are fatal to such birds as fly towards them. 



On the other hand, again, in the waters of Lake Apuscida- 

 mus, 67 in Africa, nothing will sink ; the same, too, Apion tells 



60 From K\atav, " to weep," and yeXpv, " to laugh." 



61 His credulity, we have seen already, was pretty extensive.

63 At the town called " Aquae Mattiacte," the modern Wiesbaden. 



64 In B. ii. c. 106. 



65 Sotion, professing to quote from Ctesias, says that it rejected everything 

 placed on its waters, and hurled it back upon dry land. 



66 Whence, as it was said, its name, aopi/o, 4k Without birds." Strabo 

 ridicules this story. 



67 M. Douville says that in the interior of Africa there is a lake called
