To Olympias
Having risen from the very gates of death I address this letter to the discreet lady; and I am very glad that your servants have met me just as I am anchoring at last in harbour. For had they met me when I was still tossing on the open sea, and experiencing the cruel waves of bodily sickness, it would not have been easy for me to deceive your cautious spirit, by sending good tidings instead of sorrowful. For the winter, which has become more than commonly severe, brought on a storm of internal disorder even more distressing, and during the last two months I have been no better than one dead, nay worse.
For I had just enough life to be sensible of the horrors which encircled me, and day and dawn and noon were all one night to me as I spent all my time closely confined to my bed, and in spite of endless contrivances I could not shake off the pernicious effects of the cold; but although I kept a fire burning, and endured a most unpleasant amount of smoke, and remained cooped up in one chamber, covered with any quantity of wraps, and not daring to set a foot outside the threshold I underwent extreme sufferings, perpetual vomiting supervening on headache, loss of appetite, and constant sleeplessness.
Thus restlessly did I pass through my long dark sea of troubles. But not to distress your mind by dwelling upon my miseries, from all of them I am now relieved. For as soon as spring approached, and a little change in the temperature took place, all my troubles spontaneously vanished. Nevertheless I still require great care as regards diet; therefore I put only a light load on my stomach, so that it may be able to digest it easily. But it has occasioned me no little concern to learn that my discreet mistress was brought to the verge of death.
Nevertheless in consideration of my great affection, and anxiety, and solicitude for your welfare I was relieved from this care, even before the arrival of your letters, many persons having come from thence who brought me tidings of your restoration to health.
