TJNIVEESE. 



That harmonical proportion, which compels nature to be 

 always consistent with itself, obliges us to add to the above 

 measure, 12,000 stadia ; and this makes the earth one 

 ninety-sixth part of the whole universe.

EoMAN AUTHOES QUOTED. — M. Varro\ Sulpicius Gallus^,

 T. Livius^, Cornelius Nepos', Sebosus", Calius Antipater^", 



* Marcus Terentius Varro. He was bom B.C. 116, espoused the cause 

 of Pompey against Csesar, and served as his lieutenant in Spain. He 

 afterwards became reconciled to Ctesar, and died in the year B.C. 26. He 

 is said to have written 500 volumes, but nearly all his works are lost 

 (destroyed, it is said, by order of Pope Gregory VII.). His only re- 

 mains are a Treatise on Agricvdtvire, a Treatise on the Latin Tongue, 

 and the fragments of a work called Analogia. 



2 C. Sulpicius Gkllus was Consul in the year 166 B.C. He wrote a 

 Roman History, and a work on the Echpses of the Sun and Moon. 



' Titus Vespasianus, the Emperor, to whom Pliny dedicates his work. 

 His poem is mentioned in c. 22 of this Book. See pages 1, 2, and 55 of 

 the present volume. 



4 It is most probable that Quintus -^lius Peetus Tubero is here meant. 

 He was son-in-law, and, according to Cicero, nephew of ^mihus Paulus, 

 and Consul in the year B.C. 167. There are two other persons found 

 mentioned of the name of Q. -(Elius Tubero. 



* The freedman and amanuensis of Cicero. He was a man of great 

 learning, and was supposed to have invented short-hand. He also wrote 

 a Life of Cicero. 



^ Lucius Calpumius Piso Frugi. He was Consul in the year B.C. 133, 

 and was a stout opponent of the Gracchi. He wrote Annals of the History 

 of Rome from the earliest periods. 



^ Livy, the well-known Roman historian. 



8 He was the intimate friend of Cicero, and wrote Chronicles or Annals, in 

 three books, a Life of Cicero, and some other historical works. A work still 

 exists, called " Lives of Eminent Commanders," which is ascribed some- 

 times to him and sometimes to one ^milius Probus, a writer of the reign 

 of Theodosius. The latter probably abridged the original work of Nepos. 



3 Statins Sebosus. He is mentioned by Cicero as the friend of Catulus. 

 He wrote a work called the " Periplus," and another on the Wonders of 

 India. 



1" A Roman historian and lawyer, who flourished about B.C. 124. He 

 wTote a Book of Annals, in which was contained a valuable account of 

 the Second Punic war. This work was epitomized by Brutus and held 

 in high estimation by the Emperor Adrian.
