BOOK VI. XXXIX. 217-220 



Etruria, Pisa, Luna, Lucca, Genoa, Liguria, An- 

 tibes, Marseilles, Narbonne, Tarragon, the middle 

 of Tarragonian Spain ; and then runs through 

 Lusitania. A 9-ft. gnomon throws an 8-ft. shadow. 

 The longest day-time is 15,^, , or, according to Nigidius, 

 15i equinoctial hours. 



The seventh division starts from the other side 

 of the Caspian Sea and passes above Collat, the 

 Straits of Kertsch, the Dnieper, Tomi, the back 

 parts of Thrace, the TribalH, the remainder of Illyria, 

 the Adriatic Sea, Aquileia, Altinum, Venice, Vi- 

 cenza, Padua, Verona, Cremona, Ravenna, Ancona, 

 Picenum, the Marsians, Paelignians and Sabines, 

 Umbria, Rimini, Bologna, Piacenza, Milan and all 

 the districts at the foot of the Apennines, and across 

 the Alps Aquitanian Gaul, Vienne, the Pyrenees 

 and Celtiberia. A 35-ft. gnomon throws 36-ft. 

 shadows, except that in part of the Venetian district 

 the shadow and the gnomon are equal. The longest 

 day-time consists of 151' equinoctial hours. 

 , Up to this point we have been setting forth the 

 results worked out by the ancients. The rest of the 

 earth's surface has been allotted by the most careful 

 among subsequent students to three additional 

 parallels : from the Don across the Sca of Azov and 

 the country of the Sarmatae to the Dnieper and so 

 across Dacia and part of Germany, and including 

 the GaUic provinces forming the coasts of the Ocean, 

 making a parallel \\-ith a sixteen-hour longest day ; 

 the next across the Hyperboreans and Britain, with 

 a seventeen-hour day ; the last the Scythian parallel 

 from the Ripaean mountain-range * to Thule,* in 

 which, as we said above, there are alternate 

 periods of perpetual dayHght and perpetual night.
