The boyhood of Seneca fell in the last years of the Emperor Augustus,
when, in spite of the general decorum and amiability of their ruler,
people began to see clearly that nothing was left of liberty except the
name. His youth and early manhood were spent during those
three-and-twenty years of the reign of Tiberius, that reign of terror,

Caius Caesar was the son of Germanicus and the elder Agrippina.
Germanicus was the bravest and most successful general, and one of the

and foulest of the human race. So, however, it was; and it is a
remarkable fact that scarcely one of the six children of this marriage
displayed the virtues of their father and mother, while two of them,
Caius Caesar and the younger Agrippina, lived to earn an exceptional
