of the Sun which happened before the Kalends of May, when 

 Vipsanus and Fonteius were Consuls (and that was not many 

 Years past) was seen in Campania between the seventh and 

 eighth Hours of the Day : but Corbulo (a Commander then 

 in Armenia) made Report, that it was seen there between the 

 tenth and eleventh Hours of the same Day : which was be- 

 cause the Compass of the Globe discovereth and hideth some 

 Things to some, and other to others. But if the Earth were 

 level, all Things should appear at once to all Men ; for neither 

 would one Night be longer than another, nor would the Day of 

 twelve Hours appear equal to any but to those that are seated 

 in the midst of the Earth, which now in all Parts agree toge- 

 ther alike. 



CHAPTER LXXI. 



What is the Reason of the Daylight upon the Earth? 



AND hence it is, that it is neither Night nor Day at one 

 Time in all Parts of the World ; because the Opposition of 

 the Globe bringeth Night, and the Circuit thereof the Day. 

 This is known by many Experiments 1 . In Africa and Spain 

 there were raised by Annibal, high Watch-towers : and in 

 Asia, for the Fear of Pirates, the like Help of Beacons was 

 erected. Wherein it was observed oftentimes, that the Fires 

 giving Warning before (which were set on Fire at the sixth 

 Hour of the Day), were descried by them that were farthest 

 off in Asia, at the third Hour of the Night. Philonides, the 

 Courier of the same Alexander, despatched in nine Hours of 

 the Day 1200 Stadia, as far as from Sicyone to Elis : and 

 from thence again (although he went down Hill all the Way) 

 he returned oftentimes, but not before the third Hour of the 

 Night. The Cause was, because he had the Sun with him in 

 his Setting out ; and in his Return to Sicyon he went against 

 it, and ere he came home, left it in the West behind. Which 

 is the Reason also, that they who by Daylight sail Westward 

 in the shortest Day of the Year, pass along more Way than 

 those who sail all the Night long at the same Time, because 

 the others accompany the Sun.
