the watch at night (who says) Show me the pass
(the Roman tessera).Polybius vi. 36. Have you the signal from nature
which the appearance that may be accepted ought to
have? And finally whatever means are applied to the
body by those who exercise it, if they tend in any way
towards desire and aversion, they also may be fit means
of exercise; but if they are for display, they are the indications of one who has turned himself towards something
external and who is hunting for something else and who
looks for spectators who will say, Oh the great man. For
this reason Apollonius said well, When you intend to
exercise yourself for your own advantage, and you are
thirsty from heat, take in a mouthful of cold water, and
spit it out and tell nobody.Schweighaeuser refers to Arrian's Expedition of Alexander (vi.
26) for such an instance of Alexander's abstinence. There was an
Apollonius of Tyana, whose life was written by Philostratus: but it
may be that this is not the man who is mentioned here.
