A History of Rome, Vol 1 During the late Republic and early Principate

Excerpt

This work will be comprised in six volumes.  According to the plan which
I have provisionally laid down, the second volume will cover the period
from 104 to 70 B.C., ending with the first consulship of Pompeius and
Crassus; the third, the period from 70 to 44 B.C., closing with the
death of Caesar; the fourth volume will probably be occupied by the
Third Civil War and the rule of Augustus, while the fifth and sixth will
cover the reigns of the Emperors to the accession of Vespasian.
