Further, when he was sold as a slave, he endured it most nobly. For on a voyage to Aegina he was captured by pirates under the command of Scirpalus, conveyed to Crete and exposed for sale. When the auctioneer asked in what he was proficient, he replied, “In ruling men.” Thereupon he pointed to a certain Corinthian with a fine purple border to his robe, the man named Xeniades above-mentioned, and said, “Sell me to this man; he needs a master.” Thus Xeniades came to buy him, and took him to Corinth and set him over his own children and entrusted his whole household to him. And he administered it in all respects in such a manner that Xeniades used to go about saying, “A good genius has entered my house.”
Monimus of Syracuse was a pupil of Diogenes; and, according to Sosicrates, he was in the service of a certain Corinthian banker, to whom Xeniades, the purchaser of Diogenes, made frequent visits, and by the account which he gave of his goodness in word and deed, excited in Monimus a passionate admiration of Diogenes. For he forthwith pretended to be mad and proceeded to fling away the small change and all the money on the banker's table, until at length his master dismissed him; and he then straightway devoted himself to Diogenes. He often followed Crates the Cynic as well, and embraced the like pursuits; whereupon his master, seeing him do this, was all the more persuaded that he was mad.
