To his contemporaries Cicero was primarily the great forensic and political orator of his time, and the fifty-eight speeches which have come down to us bear testimony to the skill, wit, eloquence, and passion which gave him his pre-eminence. But these speeches of necessity deal with the minute details of the occasions which called them forth, and so require for their appreciation a full knowledge of the history, political and personal, of the time.

The letters, on the other hand, are less elaborate both in style and in the handling of current events, while they serve to reveal his personality, and to throw light upon Roman life in the last days of the Republic in an extremely vivid fashion.
