Reading about the guns of August puts me in the mood for Herodotus:
And now, as he looked and saw the whole Hellespont covered with the vessels of his fleet, and all the shore and every plain about Abydos as full as possible of men, Xerxes congratulated himself on his good fortune; but after a little while he wept.
Then Artabanus, the king’s uncle (the same who at the first so freely spake his mind to the king, and advised him not to lead his army against Greece), when he heard that Xerxes was in tears, went to him, and said:-
“How different, sire, is what thou art now doing, from what thou didst a little while ago! Then thou didst congratulate thyself; and now, behold! thou weepest.”
“There came upon me,” replied he, “a sudden pity, when I thought of the shortness of man’s life, and considered that of all this host, so numerous as it is, not one will be alive when a hundred years are gone by.”
