Summarize this text:
"Turning to the sons or brothers of the dead, I see an arduous struggle before you. When a man is gone, all are wont to praise him, and should your merit be ever so transcendent, you will still find it difficult not merely to overtake, but even to approach their renown. The living have envy to contend with, while those who are no longer in our path are honoured with a goodwill into which rivalry does not enter. On the other hand, if I must say anything on the subject of female excellence to those of you who will now be in widowhood, it will be all comprised in this brief exhortation. Great will be your glory in not falling short of your natural character; and greatest will be hers who is least talked of among the men, whether for good or for bad.
"My task is now finished. I have performed it to the best of my ability, and in word, at least, the requirements of the law are now satisfied. If deeds be in question, those who are here interred have received part of their honours already, and for the rest, their children will be brought up till manhood at the public expense: the state thus offers a valuable prize, as the garland of victory in this race of valour, for the reward both of those who have fallen and their survivors. And where the rewards for merit are greatest, there are found the best citizens.
"And now that you have brought to a close your lamentations for your relatives, you may depart."
