 embrocations on the human frame, the ancient magicians 

 found their most available resources. 



The secret use which was thus made of scientific dis- 

 coveries and of remarkable inventions, has no doubt 

 prevented many of them from reaching the present times ; 

 but though we are very ill informed respecting the 

 progress of the ancients in various departments of the 

 physical sciences, yet we have sufficient evidence that 

 almost every branch of knowledge had contributed its 

 wonders to the magician's budget, and we may even 

 obtain some insight into the scientific acquirements of 

 former ages, by a diligent study of their fables and their 

 miracles.

 with some of their best deceptions. The imitation of 

 thunder in their subterranean temples could not fail to 

 indicate the presence of a supernatural agent. The

 in the work of deception. The marvellous fountain 

 which Pliny describes in the Island of Andros as dis- 

 charging wine for seven days, and water during the rest 

 of the year, the spring of oil which broke out in Rome
