Mr. Crowder smiled. "None of Apelles's paintings are in existence now," he answered. " While I was acting as model to Apelles—and I may remark that I never grew tired of standing in the position he desired—I listened with great satisfaction to the conversations between him and the friends who called upon him while he was at work.

So, in course of time, after having visited him a good deal, I made up my mind to quit the study of art and go into that of medicine.
"I got on very well, and after a time I practised with him in many cases, and he must have had a good deal of confidence in me, for when the King of Persia sent for him to come to his court, offering him all sorts of munificent rewards, Hippocrates declined, but he suggested to me that I should go.
