The collection of Cicero's Letters here reproduced in Latin with an introduction and notes is intended to be as representative as possible of the whole collection which has descended to modern times. The collection is rich in the letters Cicero wrote to the members of his family and friends. A sufficient number of letters bearing upon political matters have been included to present a good outline of Cicero's public life and the life of his times. Professor Abbott's introduction and commentary discuss the characteristics of epistolary and colloquial Latin, though no attempt has been make to give an exhaustive statement in this regard.
