2. A Pythagorean, and friend of Pythias or Phintias, who was a member of the same sect. When
the latter was condemned to die for a plot against Dionysius I. of Syracuse, he asked leave of
the tyrant to depart for the purpose of arranging his domestic affairs, promising to find a
friend who would be pledge for his appearance at the time appointed for his punishment. To the
surprise of Dionysius, Damon unhesitatingly offered himself to be put to death instead of his
friend, should he fail to return. Phintias arrived just in time to redeem Damon, and Dionysius
was so struck with this instance of firm friendship on both sides, that he pardoned the
criminal, and entreated to be admitted as a third into their bond of brotherhood. (Diod. x.
Fragm. 3; Iamblich. Vit. Pyth. 33; Cic. de Off. 3.10, Tusc. Quaest. 5.22; Ext. 1.)
