Letters 83.23

Alexander, whom I have just mentioned, passed through his many marches, his many battles, his many winter campaigns (through which he worked his way by overcoming disadvantages of time or place), the many rivers which flowed from unknown sources, and the many seas, all in safety; it was intemperance in drinking that laid him low, and the famous death-dealing bowl of Hercules.
