1 Marcus Terentins Yarro. He was born B.C. 116, espoused the cause 
of Pompey against Caesar, and served as his Heutenant in Spaia. He 
afterwards became reconciled to Csesar, 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 Grregory YII.). His only re- 
mains are a Treatise on Agriculture, a Treatise on the Latin Tongue, 
and the fragments of a work called Analogia. 
2 C. Sulpicius Grallus was Consul in the year 166 B.C. He vn'ote a 
Boman History, and a work on the Echpses of the Sun and Moon. 
3 Titus Yespasianus, 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. 
^ It is most probable that Quintus ^Hus Psetus 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. ^hus 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 Calpurnius Piso Erugi. He was Consul in the year B.C. 133, 
and was a stout opponent of the Grracchi. He wrote Annals of the History 
of Rome from the earhest periods. 
7 Livy, the well-known Boman historian. 
s He was the intimate friend of Cicero, and vn*ote 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. 
5 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. 
10 A Roman historian and lawyer, who flourished about B.C. 124. He 
wrote 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.
