Tiberius and Caius Gracchus

In this state she lost most of her children, but three survived; one daughter, who married Scipio the Younger, and two sons, Tiberius and Caius, whose lives I now write. These sons Cornelia reared with such scrupulous care that although confessedly no other Romans were so well endowed by nature, they were thought to owe their virtues more to education than to nature.

Now, just as, in spite of the likeness between Castor and Pollux as they are represented in sculpture and painting, there is a certain difference of shape between the boxer and the runner, so in the case of these young Romans, along with their strong resemblance to one another in bravery and self-command, as well as in liberality, eloquence, and magnanimity, in their actions and political careers great unlikenesses blossomed out, as it were, and came to light. Therefore I think it not amiss to set these forth before going further.
