A quote
But I was suffering too grievously to think of the danger, since a sluggish seasickness which brought no relief was racking me, the sort that upsets the liver without clearing it. Therefore I laid down the law to my pilot, forcing him to make for the shore, willy-nilly. When we drew near, I did not wait for things to be done in accordance with Vergil’s orders, until Prow faced seawards or Anchor plunged from bow; I remembered my profession as a veteran devotee of cold water, and, clad as I was in my cloak, let myself down into the sea, just as a cold-water bather should.
