most admirable and immortal spirit, as it were of a divine 

 nature, should be ascribed to Anaximander the Milesian, 

 who, they saj, warned the Lacedaemonians to beware of their 

 city and their houses \ For he predicted that an earthquake 

 was at hand, when both the whole of their city was destroyed 

 and a large portion of Mount Taygetus, which projected in 

 the form of a ship, was broken off, and added farther ruin to 

 the previous destruction. Another prediction is ascribed to 

 Pherecydes, the master of Pythagoras, and this was divine ; 

 by a draught of water from a well, he foresaw and predicted 

 that there would be an earthquake in that place^. And if 

 these things be true, how nearly do these individuals ap- 

 proach to the Deity, even during their lifetime! But I 

 leave every one to judge of these matters as he pleases. I 

 certainly conceive the winds to be the cause of earthquakes ; 

 for the earth never trembles except when the sea is quite 

 calm, and when the heavens are so tranquil that the birds 

 cannot maintaia their flight, all the air which should support 

 them being withdrawn^ ; nor does it ever happen until after 

 great winds, the gust being pent up, as it were, in the 

 fissures and concealed hollows. Por the trembling of the 

 earth resembles thunder in the clouds ; nor does the yawning 

 of the earth differ from the bursting of the lightning ; the 

 enclosed air struggling and striving to escape^.

The earth is shaken in various ways, and wonderful effects 

 are produced^ ; in one place the walls of cities being thrown

 Cicero, who employs the words " ut urbem et tecta linquerent." De Divin. 

 i. 112. 2 This anecdote is also referred to by Cicero, de Div. ii. 



* It has been observed that earthquakes, as weE. as other great con- 

 vulsions of nature, are preceded by calms ; it has also been observed 

 that birds and animals generally exhibit certain presentiments of the 

 event, by something peculiar in their motions or proceedings ; this cir- 

 cumstance is mentioned by Aristotle, Meteor, ii. 8, and by Seneca, Nat. 

 Qugest. vi. 12. 



* It is scarcely necessary to remark, that this supposed resemblance 

 or analogy is entirely without foundation. The phieenomena of earth- 

 quakes are described by Ai-istotle, De Mimdo, cap. 4, and Meteor, ii. 

 7 and 8 ; also by Seneca in various parts of the 6th book of his Qusest. Nat. 



* On this subject we shall find much curious matter in Aristotle'e 

 Treatise de Mundo, cap. 4.
