[Euclides] left the banquet and, after writing a pamphlet upon the logical problem, ended his days in despondency. Upon him too I have written lines:
Diodorus Cronus, what sad fate Buried you in despair, So that you hastened to the shades below, Perplexed by Stilpo's quibbles? You would deserve your name of Cronus better If C and R were gone.
The successors of Euclides include Ichthyas, the son of Metallus, an excellent man, to whom Diogenes the Cynic has addressed one of his dialogues; Clinomachus of Thurii, who was the first to write about propositions, predications and the like; and Stilpo of Megara, a most distinguished philosopher, of whom we have now to treat.
