It was on the cards, it seems, that our modern world should not be altogether destitute of noteworthy and memorable’ men, but should produce enormous physical prowess and a highly philosophic mind. I speak with reference to the Boeotian Sostratus, whom the Greeks called Heracles and believed to be that hero, and especially to Demonax, the philosopher. Both these men I saw myself, and saw with wonderment: and under one of them, Demonax, I was long a student. I have written about ‘Sostratus elsewhere, The treatise is lost. and have described his size and excessive strength, his open-air life on Parnassus, his bed that was no bed of ease, his mountain fare and his deeds (not inconsistent with his nameThe nickname Heracles.) achieved in the way of slaying robbers, making roads in‘untravelled country and bridging places hard to pass.
